Crashes upon simple sequence of posting messages

[myell0w]

could you provide additional information (Crash Log, Setup, iOS version, ...), it doesn't crash if I copy your code into my sample project, it runs w/o problems.

Thanks!

Crashes for me at line 687 while trying to invoke [self.messageQueue removeLastObject]. The reason is:
*** -[NSMutableArray removeObjectAtIndex:]: index 0 beyond bounds for empty array.

When I don't have switched on "Stop on Objective-C exceptions" the above exception is caught and ignored by CoreAnimation.

The stack trace is as follows:
#0 0x01a5b5a8 in objc_exception_throw
#1 0x018ffadf in -[NSArrayM removeObjectAtIndex:]
#2 0x018fbbf7 in -[__NSArrayM removeLastObject]

I turned "Stop on Objective-C exceptions" on and it still doens't crash, could you upload another sample project with the latest version of MTStatusBarOverlay where this happens? By the way, thanks for testing things out!
