DKImagePickerController: Infinite loop in DKImageManager.fetchImageDataForAsset

I am experiencing an infinite loop sometimes when running DKImageManager.fetchImageDataForAsset. On line 137 the method calls itself resulting in a loop and eventually crash.

Here’s a part of (since it repeats itself) my stack trace:
