Description sansar22 2011-09-15 12:53:30 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: Trying to shut down my laptop via KDE menu.

- Unusual behavior I noticed:  Everytime i've been doing this since this week's upgrade KDE always crashes on shutdown

- Custom settings of the application:  I'm not sure how to answer this question.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault

Comment 2 Chao Feng 2013-05-05 05:48:02 UTC
Do you still have this crash?
Comment 3 Martin Flöser 2013-05-28 20:05:39 UTC
Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid.

Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times.

If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
