When using the Dolphin file manager in KDE4.1, opening a workgroup under Samba Shares in the Network view causes a crash, when using Expandable Folders and Detail View.  Below is the sequence of events.

Launch Dolphin
Enable 'Expandable Folders' in Settings>Configure Dolphin>View Modes>Details
Open 'Network' link on navigation bar
Switch to 'Details' mode and click 'Samba Shares'
Click the '+' (plus) sign next to a workgroup and Dolphin crashes with a SIGSEV.

Below is the crashlog.

Application: Dolphin (dolphin), signal SIGSEGV
