-- Information about the crash:
Editing an image crashes the program, sometimes immediately after I right-click on the image and choose "edit", sometimes after the image editor opens and I try some operation.  On this occasion it was trying "Enhance -> Sharpen" from the image editor menu.

The crash can be reproduced everytime.
