Description Andreas 2011-09-25 19:57:01 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
I have two control lines, one on top, one on the right side. At the right side I have two systrays, one of them as standard, the second one (placed on near top of screen) only for system messages. I added a third systray to the top control panel (intention: to get a second kmix). So far everything OK.

Then trying to opt out everything but kmix. Clicking OK, plasma crashed. systray was still present, but with all options on.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Segmentation fault

Comment 1 Andreas 2011-09-25 20:06:44 UTC 
Following could be a reason:

I unselected ALL possible options in the check box list of messages in the settings window. May be controling of at least ONE selected option as default could help. It appeared, that the control panel was drawn without any symbol, then was redrawn with the previously last single option activated.
Comment 2 Dario Andres 2011-09-29 13:18:07 UTC 
[Comment from a bug report cleaner]
This is likely to be bug 241685, which has the same backtrace. It also contains references to the System Tray widget.

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

- What I was doing when the application crashed:
I have 2 systrays, on KDE 4.7.0 all works, but after updating to 4.7.1-git I got crashes on every startup.

-- Backtrace (Reduced):
