Bug 306526

Application: kded4 ($Id$)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

Started up Kubuntu and saved session was resumed. The wifi was asking for kde wallet password, I entered it and the KDE Daemon crashed & Wifi icon in notification area disappeared and went wonky. 
It all resumed back to normal after it restarted itself and was able to connect to the wifi.

-- Backtrace:
Application: KDE Dæmon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
