Application that crashed: dolphin
Version of the application: 1.2.80
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
These are the steps that caused the crash:

1) I entered the URL 'fish://<hostname>' (the hostname was not fully qualified, the domain is among my search domains in resolv.conf)
2) Dolphin presented three separate authentication dialogs and one kwallet dialog
3) I entered the kwallet password and then entered the ssh authentication information in all dialogs
4) Dolphin UI froze for a long time until I got fed up and hit the window close button, at which time I got the crash.

Hope this helps.
