Comment 3 Dario Andres 2010-04-04 17:42:26 UTC 
Reopening as this seems to be a separate issue (doesn't have "discard()" in the backtrace, and it is still unfixed in KDE SC 4.4.2: bug 233128)
Comment 4 Dario Andres 2010-04-04 17:42:57 UTC 
From bug 233128:
-- Information about the crash:
Probably related to other bug reports.  Appears that after a number of kwin
crashes that kwin effects were turned off which seems to have a connection. 
Now plasma desktop, kwin and krunner all crash leaving black desktop.
The crash can be reproduced every time.
Comment 5 Dario Andres 2010-04-04 17:45:27 UTC 
More information from bug 233128 (also contains a .xsession-errors log):
---
I figured out that my /var partition had filled up with package cache.  After
expanding it I'm back in KDE heaven.  I loaded up Gnome to have a desktop until
I figured out what the problem was.  Gnome actually warned me about the full
/var partition.  That would probably be a nice check for KDE to do.

Comment 7 Dario Andres 2010-04-10 23:47:56 UTC 
From bug 233959:
-- Information about the crash:
Plasma crashed when browsing the internet, using Chrome and viewing video in
flash, I can support other info if you tell me what sort of :)
The crash can be reproduced some of the time.

Comment 9 Dario Andres 2010-04-11 00:07:28 UTC 
From bug 232620:
-- Information about the crash:
Directly after update krunner fails every 2 second

From bug 232846 (4.4.2):
-- Information about the crash:
Plasma crashed when I activate "Composite image". Every time I'm changing this option, the Plasma crashes.

From bug 233960 (4.4.2):
-- Information about the crash:
KRunner crashes randomly on my PC, sometimes it takes the whole
plasma-desktop with it...

Comment 16 Christoph Feck 2012-10-05 01:41:04 UTC 
Plasma::Theme no longer uses KPixmapCache, so this crash can no longer happen.
