App crashes with reason: Collection <__NSArrayM: 0x7071700> was mutated while being enumerated

Question

Can you please help me to find reason why my app crashes after clicking on segmented control? Not allways, but usualy after some clicks.

Looks like the problem was with UIImagePickerController and only in simulator (more described in details here: http://blog.airsource.co.uk/index.php/2008/11/12/memory-usage-in-uiimagepickercontroller/ ). On real device everything works quite fine.
