My app crashes with "Program received EXC_BAD_ACCESS" error iphone - iphone

Question

When my app launches from BACKGROUND , I am running a new thread to get AddresssBook data using notification center. Here is my code which shows how I call the method
-(void)appLaunchedFromBackground:(NSNotification *) notification {
// NSThread *backgroundThread; is my ivar
backgroundThread = [[NSThread alloc]initWithTarget:self selector:#selector(getUpdatedAddressBookData) object:nil];
[backgroundThread start];
}
-(void)getUpdatedAddressBookData {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
AddressBook *addBook = [[AddressBook alloc]init];
[addBook fetchAddressBookDataInBackground];
[addBook release];
[pool drain];
}
Here is my code for fetchAddressBookDataInBackground method
-(void)fetchAddressBookDataInBackground {
if (self.tempArray == nil) {
NSMutableArray *temp = [[NSMutableArray alloc]init];
self.tempArray = temp;
[temp release];
}

}
But my app crashes with "Program received EXC_BAD_ACCESS" error at any line where I am using "ABRecordCopyValue" function . What I am missing? I am not getting whats wrong in my code?
I tried setting NSZombieEnabled = YES , but its not showing any message. Just saying "Program received EXC_BAD_ACCESS" at any line using ABRecordCopyValue function & in console I see (gdb) thats it.
Any knid of help is highly appreciated. Thanks.
