Description David Zhang 2011-02-02 04:20:58 UTC

Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

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

I grouped two windows together, and then right clicked on to do the shading, and then switched to the other window, KWin crashed. Every time.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Comment 1 Thomas Lübking 2011-02-02 22:30:27 UTC

Which decoration? Oxygen?
Though not a clear dupe of the others (no bridge invocation here) i can't reproduce (4.6) so it might have (implicitly? - shade strategy code also changed) fixed meanwhile.

Comment 2 David Zhang 2011-02-03 00:56:13 UTC

Yes, it's Oxygen. Let me know if u need more details. 
Thanks.

Comment 3 Thomas Lübking 2011-02-04 22:19:47 UTC

please test with 4.6.x if you can

Comment 4 Martin Flöser 2011-05-07 10:13:56 UTC

waiting for test results. Please reopen if you are able to reproduce with 4.6
