Bug 296418

Application: kactivitymanagerd (1.0)
KDE Platform Version: 4.8.1 (4.8.1) "release 483"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
loggin into my computer

sometimes, kactivitymanager crashes, sometimes it doesn't. I'm not actually "doing" anything, other than logging in and having my saved session restored.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE-Aktivitätenverwaltung (kactivitymanagerd), signal: Segmentation fault
