Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
 - lmb click in dophin location line
 - type "smb://<hostname>" in location line with the host running windows 7 and providing one share (it is the only one) with access only for host user accounts (default settings used of sharing wizard in windows 7)

=> dialog appears requesting account details

 - enter username (mine contains a '-', letters only else)
 - enter password (only letters and numbers)

=> segfault

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