- Does the application crash again if you repeat the situation you described ?

Comment 4 hayleyhung 2010-04-08 15:09:26 UTC
It's a really strange thing. 
I started having problems yesterday and rebooting a few times didn't solve the problem. Then I tried just logging into KDE and each time I tried, it would refresh the screen and go straight back to the login screen. I tried logging into gnome instead and there was an error saying I'd run out of disk space, and sure enough, / was completely full. The strange thing is that this was one of the first things I checked and before I booted up the previous time, there was 2.1 gb of free space. I cleared up some space and it seems to be working again. But I can't figure out what suddenly used up all that space while rebooting my machine. The only thing I have been using that might have filled up space is backintime, which I have just started using. The backups are all stored on a completely different partition but I did set up a new directory to be backed up yesterday.. which was pretty huge. At some point, I heard lots of hard disk activity. I'm not sure how backintime does the initial file transfer .. but this could be one possible explanation for the constant crashing. Now I've got back to 1 gb of free space, it's all going ok again.. for the time being.

From bug 233700:
-- Information about the crash:
I was trying to switch on desktop effects. Desktop effects seem really unstable
- they were on before I switched off my machine but when I restarted, desktop
effects switched off. When I restarted, the system was also acting slowly. I
tried to start system settings a few times but the cursor bounced with no
response. Finally when system settings was able to start, I enabled desktop
effects, it crashed.

Comment 9 Michael Pyne 2010-05-19 00:07:48 UTC
Either it's a bug in KPixmapCache (used by Plasma::Theme) or the cache is corrupt. To "fix" a corrupt cache just delete it.
i.e. rm /var/tmp/kdecache-$USER/kpc/*.{index,data}

If the bug is in KPixmapCache then it is fixed for KDE SC 4.5, as Plasma::Theme no longer uses KPixmapCache. The fix is unfortunately far too invasive to backport to KDE 4.4.
