it seems you are using multiThreading for network operations.
in case you calling your thread from UIViewContoller please look at the Deallocation problem:
deallocation problem
search for the paragraph deallocation problem.
thats happens when calling threads from UIViewControoler and navigating before thread finish works.
look at the link for full description of the problem.

It is particularly crashing "Thread 5 Webthread" Sometimes Thread 8
Any feedback is appreciated :)
I figured out the problem, #Jake Lin's suggestion was right it was the link. I was trying to connect to twitter and I was using the URL: http://mobile.twitter.com/account and I tried changing it to: https://mobile.twitter.com/account where I added the "s" in the http. Very strange problem but that seemed to fix it.
My application crashes when I try to scroll the tableview very fast or reload the data from remote. Everything seems to be working fine, when I let the remote fetch happen first and then scroll the tableview. I have no idea what the crash log below means. It just works fine sometimes and crashes sometime.

I would be really happy if anybody could explain me what this crash log could relate to and how I could solve it. Many many thanks to all those who are willing to help others.
Seems to me that it's dangling pointer, and you're sending message to it.
As MikeD said, use breakpoint on exception if it can help. But it's not 100% reliable since you get a SIGSEGV and not a SIGABRT. And the exception throw is not really the cause of the crash, just a border effect.
Edit
Ok: In your log crash, it says that libsystem_kernel.dylib has crashed in a kevent call. That won't help you since this is private and opaque, and you can be 100% sure this lib do its job well. This can appears because you have used (unintentionally) a space memory where you should not write into. Like with a dangling pointer. Let's say you have allocated memory to 0x2000 and you have a pointer pointing to this memory, if you freed the memory but still using this pointer to this address, if someone else (like libsystem_kernel) use it, and you change some data in the same time (because of your dangling pointer). Then the other side will use data corrupted, and some random behavior will occur. That's why if you analyze literally your crash log, you'll do wrong statement. Because kevent from libSystem is stable.
By the way you have thread 1 who crashed, but look into thread 0, it was trying to raise an exception too, but it didn't get time to do it. This can occur because of data corrupted too.
That's why I recommend you to make another crash, and compare it to this one. If the crash log are the same, then i was totally wrong. If the crash log are different, this is a dangling pointer.
The resolution center rejected my app because, as they say, it crashes on iPhone 5 with iOS 6.1.2.
I have an iPhone 4 with iOS 6.1.2 and it doesnt crash. I can't solve that problem!
They also wrote that the app crash when:
Launch the app
Login with Facebook.
App crashes when the device returns to the app.
Here the simbolicated crash log:

Here's the LetturaScrittore method that makes the app crash (I use it to write on a .txt the email of the facebook user):
- (void)writeStringToFile:(NSString*)aString {
// Build the path, and create if needed.
NSString* filePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* fileName = #"myTextFile.txt";
NSString* fileAtPath = [filePath stringByAppendingPathComponent:fileName];
if (![[NSFileManager defaultManager] fileExistsAtPath:fileAtPath]) {
[[NSFileManager defaultManager] createFileAtPath:fileAtPath contents:nil attributes:nil];
}
// The main act.
[[aString dataUsingEncoding:NSUTF8StringEncoding] writeToFile:fileAtPath atomically:YES];
}
The reason for the crash is that you don't actually pass a NSString object to writeStringToFile.
My mistake was on the facebook auth login: without the permission of the email, facebook return nothing, and the app crashes when trying to write the .txt file.
I am having a big problem figuring out where my app crash is being caused, and I'm not sure how to interpret the crash report.
The crash clearly occurs in Thread 0, but at what step might it actually be crashing in? I certainly am not manipulating CALayers in my code at all. In anyone experience, does this happen for any particular reason?

UIViews are implemented with CALayers, so if you are using UIKit, you are using layers. My guess is that an already released object is receiving messages. Maybe you released an object more times than you should. Try recompiling with NSZombieEnabled.
3 UIKit 0x331b0f72 -[UIView(CALayerDelegate) drawLayer:inContext:] + 270
By any chance, did you release an objectA which is a delegate to objectB without removing the delegate assignment first, i.e. objectB.delegate = nil; [objectA release];?
I'm trying to decipher a crash report from an app in the app store; but it isn't very meaningful.
The crash file has been emailed to us, and we have tried symbolicating with the dSYM file from the original app build for the store; but none of the symbols resolve correctly; so we have reverted to using atos and running it over the binary submited to the app store along with the memory addresses in the crash file.
When we resolve the symbols using atos.

11 MyApp 0x00002b20 0x1000 + 6944
After we run atos over the memory addresses: 0x00002b6c & 0x00002b20
atos -o MyApp -arch armv7 0x00002b6c 0x00002b20
and it resolves to the following:
main (in MyApp) (main.m:14)
start (in MyApp) + 32
What could cause an app to crash in start/main ? We don't know the use case here; and are unable to resolve the symbols further up the stack.
Any help would be greatly appreciated.
Cheers

Did you check some object released, which send message ? My English is not good, I give some example as following.
NSString *aReleasedStr = [[NSString stringWithString:#"test"] release]; //< released
int aIntVal = [aReleasedStr intValue]; ///< crash
I encountered such crash report before, when I send a message with a released object. Maybe you can check such cases.
