Description Wonko 2011-04-19 00:00:37 UTC 
Application: kded4 ($Id$)
KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-ck x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
kde4init crashes 1-4 times per day here.  I did not care much about it, because I did not notice any negative impact. I also thought it was related to plasma crashing all the time (see bugs 226596/258706), as both kde4init and plasma-desktop sometimes crashed at the same time. But now that I disabled the system tray, plasma no longer crashes. Still, kde4init does sometimes.

Drkonqui suggests this may be a duplicate of 248004, but the backtrace looks quite different to me, so I filed a new bug. If you like, I can build stuff with debug information.

Not sure if this is related in any way, but sometimes I also have

The crash can be reproduced some of the time.

Argh, didn't want to send this yet, and wait at least until it happens again. I thought I had to press the 'Finish' button in Drkonqui to send the report, but apparently pressing 'Next' was enough. So now the bug is filed, sorry.

What I was about to write is that sometimes I have kded4 and knotify running at 100%, often there are two instances of both processes, which gives four processes eating all CPU time. Not sure if this is in any way related, but I think I always had kde4init crash somewhat earlier before this happens, so I thought I'd mention it. I simply kill them, then all is well for a while.
