Bug 258849

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I was notified that I had updates, so I applied them. While it was working, I (right-?)clicked the little package-arrow icon and left the menu up. When that step completed, the icon changed or went away (to be replaced by another), and Plasma crashed.

(I don't remember exactly what it was doing, but it was either updating package lists or downloading packages.)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
