Description Shlomi Fish 2014-04-17 17:46:43 UTC
Application: kwin (4.11.7)
KDE Platform Version: 4.12.97
Qt Version: 4.8.5
Operating System: Linux 3.13.10-desktop-1.mga5 x86_64
Distribution: "Mageia 5"

-- Information about the crash:
- What I was doing when the application crashed:

In the shell, I ran «valgrind "$HOME"/apps/kalgebra-TO_DEL/bin/kalgebra"» and then I pressed the "Kickoff" menu item on the panel.

- Unusual behavior I noticed:

KWin crashed.

- Custom settings of the application:

Also happens in a new user.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin), signal: Illegal instruction

New crash information added by DrKonqi

kwin (4.11.10) on KDE Platform 4.12.5 using Qt 4.8.6

Similar crash, same circumstances... running an application under valgrind takes down kwin. For me this is 100% reproducible with a development build of Slicer (http://www.slicer.org/), although that's a bit excessive as a test case, but valgrind, and not the specific application running in valgrind, appears to be the critical component.

Comment 2 Matthew Woehlke 2014-07-23 15:28:38 UTC
FWIW I can confirm that the same thing happens with 'valgrind /usr/bin/kcalc'.

No crashes (but my Kickoff button is for Homerun Applet, so I'll try again with that as well, or see if I can find the bug from the bt itself).
Comment 4 Michael Pyne 2014-07-27 03:11:52 UTC
Likewise with real Kickoff. It's annoying in that regard being the KSharedDataCache maintainer—it really doesn't *ever* crash for me, only for others! :(

Comment 6 Dominik Haumann 2016-09-06 11:55:20 UTC
This issue unfortunately still exists see bug #361426. There, you also can find a backtrace of KAte crashing with a recent version (2016-09-06).
