Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
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:
It must have to do with samba because exce[t from dolphin's crash there are many times access is denied in the shared drives. samba keeps asking for user name and password but nothing happens next; eventualy Dolphin crashes.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
