-- Information about the crash:
I opened a samba folder (which has the login credentials saved in kde wallet) resulting in a crash. In addition Dolphin did not remember the samba password even though they exist in the wallet.

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".
