Application: kded4 ($Id: kded.cpp 1031637 2009-10-05 16:58:19Z lunakl $)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-686 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
Each time KDE 4 starts, after a few minutes, a message will appear talking about a bug.
I changed some tray icons to hidden, but when they weren't hidden, everything would get ugly.
A new KMix icon appeared and Network Manager went over the clock and so on...

 -- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
