Google Analytics 3.12 crashes on iOS

I'm new to iOS development and I have a crash on my iOS app (developed by vendor). I have learnt to read logs and this is what I see:

2015-06-15 19:00:51.628 my_app[2540:113596] WARNING: GoogleAnalytics 3.12 void GAIUncaughtExceptionHandler(NSException *) (GAIUncaughtExceptionHandler.m:48): Uncaught exception: *** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array
2015-06-15 19:00:51.636 my_app[2540:113791] INFO: GoogleAnalytics 3.12 -[GAIAnalyticsPropertiesStore propertyRecordForTrackingId:] (GAIAnalyticsPropertiesStore.m:464): Record for tracking id my_tracking_id not found
2015-06-15 19:00:51.640 my_app[2540:113791] VERBOSE: GoogleAnalytics 3.12 -[GAIBatchingDispatcher persist:]

I want to know if Google Analytics is causing the crash or something else that is triggering the crash. The API calls are fine and other parts of the app are working fine.

EDIT Additonal stacktrace

Just ran into a similar issue, and have concluded that it is not Google Analytics causing the crash. Google Analytics is just merely wrapping around another crash for reporting purposes.

If you change the following setting in your App Delegate's didFinishLaunchingWithOptions: (or other location), the crash will appear as a normal error in the XCode console:

GAI *gai = [GAI sharedInstance]; gai.trackUncaughtExceptions = NO;

One way to debug this issue is to add a Symbolic Breakpoint on objectAtIndex: This may result in many hits to objectAtIndex: before the debugger hits the one you're after but it's guaranteed to find it.

Steps in Xcode 4:

View > Navigators > Breakpoint Navigator
click '+' and choose Add Symbolic Breakpoint in the pop-up
type in "objectAtIndex:" in the Symbol text field and click Done

at runtime, if you can't tell which objectAtIndex: you're hitting, move the slider at the bottom of the Debug Navigator all the way to the right.
