            Status: UNCONFIRMED

        ReportedBy: kde at pi-xi.net


Application: kded4 ($Id$)

Qt Version: 4.8.0
Operating System: Linux 3.1.6-1.fc16.x86_64 x86_64

-- 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.
