Bug 291484

Application: kded4 ($Id$)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.7-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I opened a samba folder and even though the credentials are saved in the wallet, dolphin decided to ask for them once more. after that it crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
