iOS7 beta bug

[caspahouzer]

I got the following console error on iOS7 (<= iOS6 works):

: *** Assertion failure in -[UIWindowController transition:fromViewController:toViewController:target:didEndSelector:animation:], /SourceCache/UIKit/UIKit-2872.3/UIWindowController.m:223
: Warning: Attempt to dismiss from view controller <UIImagePickerController: 0x168d9620> while a presentation or dismiss is in progress!
