Using kde4daily, KDESVNTRUNKr740861

1) Open konqueror
2) type "smb:/" into location bar
3) konqueror crashes

- Does not happen when accessing smb://host/ (whether host exists or not)
- Does not happen when eth1 is not up or has no IP address assigned - Instead, I get "Unable to find any workgroups in your local network. This might be caused by an enabled firewall."
