Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I had installed and uninstalled several widgets, and placed and removed several of them on various virtual desktops to try them out.  One of them that was kept was the gmail-plasmoid, which I had placed directly on the panel, not on a desktop.  I don't believe I had moved it at all, but I can't swear to that since I had played with a bunch of widgets over the last 24 hours. (I note this specifically because that widget is mentioned in other similar bug reports.)

Plasma-desktop did not actually crash until tried to adjust the system tray settings for which apps I wanted to appear there always versus auto or hidden.  (I note again that although I had played with a lot of widgets over the past 24 or so hours, no crash happened until today with the system tray settings.)  The first time I rebooted ok but my system tray settings had not been saved.  I re-entered my choices there, and plasma-desktop crashed again.  Now it crashes immediately when I boot, which I presume means my settings were saved, and were bad choices.

The crash can be reproduced every time.
