Bug 240031

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.81 (KDE 4.4.81 (KDE 4.5 >= 20100527)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I had lots of activities (that I hadn't knowingly created), two called "Desktop", lots called "unnamed" and several complaining that some D-Bus name wasn't provided by any service files.  I went through the list deleting all of them except the one I was using (one of the "Desktop" ones, the second one in the list).

When I deleted the first activity in the list (one of the ones complaining about the missing service name), Plasma crashed.  After it had restarted, I was able to delete the activity without a problem.  Plasma didn't crash when deleting any of the other activities.

The crash does not seem to be reproducible.

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