[TIMOB-1915] iOS: Analytics crash (SIGABRT) when using featureEvent

SDK 1.4.1.1 on iOS SDK 4.1. I figured I'd use Ti.Analytics custom events to get more info out of my app. So, I added a number of them around my codebase, using syntax such as:

Ti.Analytics.featureEvent("myevent1");
Ti.Analytics.featureEvent("myevent2", {extraData: "test"});
(seems pretty sane, along what the docs say).

However, when I start my app up, after the first analytics call the app will predictably crash within 30 seconds with EXC_CRASH (SIGABRT) and a reason of "NSMutableArray insertObject:atIndex:]: attempt to insert nil object at 0'". This crash happens in both the simulator, and on a device (both iOS 3.1.3 and 4.1). Removing just these calls and deleting/reinstalling the app on the phone/simulator makes the app run fine without crashes, and adding them back in starts the crashes again.

I've tried removing the build directory and regenerating it, and am going from a fresh install of Titanium that works fine with everything else.

P.S. Looking at AnalyiticsModule.m (http://github.com/appcelerator/titanium_mobile/blob/master/iphone/Classes/AnalyticsModule.m">http://github.com/appcelerator/titanium_mobile/blob/master/iphone/C...) line 164 could be the culprit...if for some reason what's coming back in line 163 is nil (as no validation is done to it).
