Bug 300590

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

Ich loggte mich auf dem SocialNetwork, des Desktop Gadget ein, welches standart mäßig vorinstalliert ist. Dieses Programm ist von Sebastian Kügler "Über den Social Desktop kommunizieren" Nachdem ich die Anmeldung abgesendet hatte, stürzte der komplette Desktop ab.

The crash can be reproduced every time.

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