Comment 23 for bug 560588

Maybe I found something! At least this works for me..!?

Select Applications|Accessories|Passwords and encryption keys. Then in the Passwords tab, delete the entry containing your smb share (in my case this was paul@uranium). Then close the Passwords and encryption keys application and open Nautilus. Delete any bookmarks that point to your share and close Nautilus. Reboot your PC (I'm not sure that this step is necessary). After the reboot, launch Nautilus again and hit Ctlr-L. Enter the path to your smb share following this format "smb://192.168.3.253/paul/" (192.168.3.253 is the IPaddress of my samba server uranium) and enter your smb password. Tell the system to save the password permanently and add a bookmark for your share. Following these steps you can also mount more shares. After a reboot I can simply click the bookmark and open the smb share. This is of course not the solution but only a workaround.
