GraphicsServices: GSEventRunModal crash on iPhone

Question

Been looking through crash reports online, and this seems to be the main problem.

Any idea what it is referring to? (Too many graphics, graphics are too heavy, etc.)

I haven't had any crashes in simulator or on device, oddly.

Crash log:
Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x00000000, 0x00000000

Answer 1

Since __NSThreadPerformPerform is throwing an exception deliberately, something is wrong with information passed to it. There may have been a nil pointer to something since the exception codes are zero.

One of these methods (or similar methods) may have called with bad information or the information is bad by the time it is actually run.

performSelectorOnMainThread:withObject:waitUntilDone: 
performSelectorInBackground:withObject: 
performSelector:withObject:afterDelay: 
makeObjectsPerformSelector: 

Also, another StackOverflow article has nearly the same stack and that one was caused by a corrupt Address Book entry. ( iPhone crash that only happens on one phone )
