As per the bug report, the issue was "in Ubuntu 6.10" (Edgy), in the dialog that pops up "when attempting to connect to a Samba share".
The fast way to replicate this is to hit Alt-F2 to bring up the "Run Application" dialog, and type "smb://server/share".
Alternately, you can through Places -> Connect to Server
