From bug 220602:
---
What I was doing when the application crashed:
I finished watching a video clip in VLC.  I tried to delete the file and the
plasma-desktop crashed.   It could be that the file wasn't closed yet when I
attempted the delete action.

*** Bug 272132 has been marked as a duplicate of this bug. ***

best guess: something is calling setDontShowAskAgainConfig with a pointer that gets deleted. this is a design flaw imho in KMessageBox. not plasma's problem, however.

Created attachment 82224 [details]
New crash information added by DrKonqi

plasma-desktop (4.10.5) on KDE Platform 4.10.5 using Qt 4.8.4

- What I was doing when the application crashed:
I created a single folder on the desktop view widget, right clicked it, and pressed Delete.

- Unusual behavior I noticed:
The crash occurred. The folder was still there. The widget was moved to the desktop location (0,0). Unable to reproduce.

- Custom settings of the application:
The widgets were locked. The widget was using the default folder view. The widget's size was much larger and bordering the left and bottom edges of the screen.
