I use Ubuntu 8.04 with Gnome2.22.
Sometimes, when I use "Places->Connect to Server..." to connect to some samba shares, it will show an error dialog say "Can't display the location smb://10.32.100.25/public. The specified location is not mounted ".
But in fact, the mounted icon just show on the desktop, and double click it, the samba share can be opened in nautilus.
This is not always happens, but sometimes.
