Assertion _targetImage!=null

[ChristophKe]

Situation: After cropping, onCropped and onStatusChanged with status= ready were called. At this time the crop widget still shows the progress indicator for a while loading the cropped image Following Exception when I start a new crop before the progress indicator has gone:

Is there a way to be informed when _target image is set, so I can block possibility for start new crop till this point?
