No. I used native software without using The Wine.

Comment 3 Thomas Lübking 2013-04-02 12:12:29 UTC

This is not so much about wine.

Define "something" and most importantly: can you reproduce the crash and explain how to do so?

I minimize/maximize the window, toched on the full-screen mode and then I quited from the full-screen mode, the error was written by the crash-report programm.

Comment 5 Thomas Lübking 2013-04-02 17:49:40 UTC

The bug is still a dupe and the pattern fits.
Apparently under "some" circumstances Gwenview can cause the same condition as wine/photoshop.

Whatever this condition is it looks like KWin would let some mouse event escape through to Qt.

Please attach the output of "qdbus org.kde.kwin /KWin supportInformation" to bug #288454 and leave this one a duplicate.
