iPhone App Crashing

[nazgul42]

I don't know if I'm in the right place to ask this, but here goes
With this iPhone app that I am developing, when I run it, everything works as expected. When I press the Home button to close it, gdb shows:
"*** -[NSCFString userInfo]: unrecognized selector sent to instance 0x8038
CoreAnimation: ignoring exception: *** - [NSCFString userInfo]: unrecognized selector sent to instance 0x8038
And my program keeps running, even though I pressed the Home button and opened Safari or something...
If I click my program's icon again, it goes right back to where I left it, and if I press the Home button, it actually crashes with that same error. I don't understand this because it has never happened before, and I haven't done anything that involves userInfo. Thanks for any help that you can give.

Hi, I encountered this issue developing iPad app.

In my case, I saw this message when I rotate iPad quickly.
The reason is that I use [[UIDevice currentDevice] orientation] to get current device orientation in UIViewController.
This issue is solved by changing "self.orientation".

Thanks.
