FBFriendPickerViewController Crashing - iphone

Question

a few days ago I had this working where after you login to facebook you can click a button and an FBFriendPickerViewController would appear with a list of all facebook friends. However, suddenly it has started to crash with some weird errors. Here is my code:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return [FBSession.activeSession handleOpenURL:url];
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
In my home viewcontroller.m
// Pick Friends button handler
- (IBAction)pickFriendsClick:(UIButton *)sender {
// Create friend picker, and get data loaded into it.
FBFriendPickerViewController *friendPicker = [[FBFriendPickerViewController alloc] init];
self.friendPickerController = friendPicker;
[friendPicker loadData];
// Create navigation controller related UI for the friend picker.
friendPicker.navigationItem.title = #"Pick Friends";
friendPicker.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(friendPickerDoneButtonWasPressed:)];
friendPicker.navigationItem.hidesBackButton = YES;
// Make current.
[self.navigationController pushViewController:friendPicker animated:YES];
}
// Handler for when friend picker is dismissed
- (void)friendPickerDoneButtonWasPressed:(id)sender {
[self.navigationController popViewControllerAnimated:YES];
NSString *message;
if (self.friendPickerController.selection.count == 0) {
message = #"<No Friends Selected>";
} else {
NSMutableString *text = [[NSMutableString alloc] init];
// we pick up the users from the selection, and create a string that we use to update the text view
// at the bottom of the display; note that self.selection is a property inherited from our base class
for (id<FBGraphUser> user in self.friendPickerController.selection) {
if ([text length]) {
[text appendString:#", "];
}
[text appendString:user.name];
}
message = text;
}
[[[UIAlertView alloc] initWithTitle:#"You Picked:"
message:message
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil]
show];
}
And finally here is the error message I am getting when the button set up to the pickFriendsClick method is hit:

Again, the login and logout functionality I have implemented is working great, and this was working not too long ago however now it is giving me trouble. Any help would be greatly appreciated. Thanks!
EDIT:
Okay so I added this line of code:
[friendPicker setItemPicturesEnabled:NO];
and it now works however obviously I do not get the little thumbnail profile pictures in the tableview cells.
I guess the error is that it for some reason crashes (SIGABRT) when it is trying to load the profile pictures. If anyone knows why this is that would be great, especially seeing as it worked and loaded the pictures a couple days ago.

Answer 1

Going to add your content to the answer as I came across the same issue and tldr and missed the hack solution.
The stack trace shows an exception being thrown at a line:
[FBGraphObjectTableDataSource tableView:imageForItem:]
Ergo setting:
self.friendPickerController.itemPicturesEnabled = NO;
seems to fix the issue as it won't load images.
