Application Crash - EXC_CRASH (SIGABRT) - iOS 4.3 - three20

I have included three20 library in my project. I am making use of the TTThumbsViewController. Everything was working great until i upgraded to Xcode 3.2.6 and iOS 4.3. The grid of photos appears fine, but as soon as i click on one the thumbs, the app crashes. I am certain that this is not a memory issue. It works fine on the simulator though. Here is the crash report :

Thanks

The function CALayerSetPosition is throwing an exception of type NSException, and nobody is catching it, so your application is getting terminated. Try adding this code around the call to -[UIView(Geometry) setFrame:] inside the function -[TTPhotoView layoutSubviews] (which should be on line 221 of TTPhotoView.m):

@try
{
    [myUIView setFrame:someFrame];
}
@catch(NSException *exception)
{
    NSLog(@"Caught exception: %@", exception);
}

That should give you more information about why the exception is being thrown; most likely, you're passing an invalid parameter or something.

Yes..It was a NaN that was being passed. Basically if you use the constructor(MockPhotoSource class) which by default assigns a null value to the caption variable, it throws this exception. So i used the other constructor and gave a blank value to the caption parameter

I also just recently saw this exception and per what Adam said, I believe the problem is that a NaN is being passed in as a parameter and this is throwing the exception. If it's the same problem I was facing, I was able to comment the line out to just get around the problem (AFAICT the line is only dealing with the loading spinner progress indicator). So if you're willing to live w/o that, you can get around it
