--- Comment #3 from Stefano <erist...@cryptolab.net> ---
I can reproduce this bug. When double-clicking to enter full screen, if you
inadvertently move the mouse, you'll start dragging the image thumbnail. The
drag-n-drop operation remains struck and you'll have that thumbnail attached to
the cursor even after releasing the mouse button. In this situation, every
keypress would make gwenview crash.
