In my case, I was trying to open my music folder on my Win2K3 server and getting the error. I worked around this by mounting the windows share to my Music folder in my Home directory.
sudo mount -t cifs //192.168.10.100/music ~/Music -o username=windows.username,password="mypassword",iocharset=utf8,file_mode=0777,dir_mode=0777
Of course, you'll need to edit the command to your situation.
Workaround, mount via cifs:
