When viewing a video stream via the Ultrasound plugin, the user is able to crop the image. If the croppping borders intersect (i.e. more pixels are cropped away than are available in the picture, an exception is caught and the user is advised to restart MITK.
This is a lot better than a crashing application obviously, but could be handled more gracefully.
User maerz has pushed new remote branch:
bug-17401-UltrasoundPluginBehavesErraticallyWhenUsingBadCroppingValues

Added checks against illegal crop areas
The Widget is now aware of exceptions coming from the image source and reacts accordingly by resetting the values to the last known functioning ones.
Hoewever, if e.g. cropping.left == image width, MITK crashes still. The reason ist probably an insufficient check in the image source
