Description Unknown 2010-05-21 21:25:38 UTC 
Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.34 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
Just like above… but I'm not sure what was the first crash here. Opened urxvt from krunner and after a while (around ~30 minutes or so) it just *bang* *bang* two DrKonqi almost at the same time (and when I started to report this issue KDE Daemon also crashed).

Weird plasma crash happend also before, but I was unable to make a usefull backtrace. And sometimes it was in a crash→restart→crash loop.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Przestrzeń robocza Plazmy (kdeinit4), signal: Segmentation fault

[Comment from a bug triager]
From bug 224609:
What I was doing when the application crashed:
When I start oowriter I get the proper window and when I want to open a file in
a directory it says "Error: "/var/tmp/kdecache-oyoEbr7tf" is owned by uid 1000
instead of uid 0.
Error: "/tmp/kde-oyoOv0ea9" is owned by uid 1000 instead of uid 0.
and OpenOffice window disappears. /tmp/kde-myuser is ownrd by me but somehow
root msut own it. I tried to change the ownership but still getting the same
result.

[Comment from a bug triager]
From bug 260367:
- What I was doing when the application crashed:
I accidentally filled the hard disk.
Then Lancelot showed me 4 MessageBox's about unable to open file corresponding
to 4 main categories in the menu: apps, computer, contacts, documents.
Then instead of terminating gracefully, it fell on __GI_clock_gettime.
Most of my crashes are related to some sort of issue with gettime
Comment 4 Beat Wolf 2011-12-06 10:03:44 UTC 
This crash report is against an old kde version. Can you reproduce this bug with a newer version? If yes, please reopen the bug. Thank you
