strange kcontrol crash (3.3.2)
Hi,
running sid and sid's kde 3.3.2 packages i noticed kcontrol crashing
immediately after trying to run it. I couldn't find any bug reports
related to this problem and even more confusing can't reproduce it on
another sid-system. The crashes started a few days ago, I can't say
when exactly because I don't use kcontrol regularly.
### quote from .xsession-errors ###
QPainter::begin: Cannot paint null pixmap
QPainter::setPen: Will be reset by begin()
DCOP aborting call from 'anonymous-484' to 'kcontrol'
ERROR: Communication problem with kcontrol, it probably crashed.
KCrash: Application 'kcontrol' crashing...
###
Running kcontrol --nocrashhandler creates a core with the following backtrace:
### gdb /usr/bin/kcontrol core ###

Finally the last lines of strace's output:

So I'd be glad if there was someone who could at least give a small
hint about what might be the problem.
Thx
