Bug 255262

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Everytime I logout or restart my computer, plasma-desktop crashes, making the bug reporter appear.

This bug also existed in Kubuntu 10.04 on the same computer. However, it has gotten worse in 10.10 : it prevents KDE from completely shutting down until I press the "Close" button on the bug reporter. In 10.04, the bug reporter appeared but the computer did shut down without any intervention.

From what I can tell this bug was supposed to be fixed. Maybe it's a different issue altogether.

The crash can be reproduced every time.
