Description of problem:
Browsing & mounting of remote Windows (server 2003) share seems to work properly.  I can copy files from the shares but when I attempt to copy a file to a share I get an error message:
Error while copying "filename"
There was an error copying the file into smb://server/scans/transfer
(clicking on show more details): Invalid Argument
If I hit cancel an empty file is created in the folder, if I hit skip it skips it.

Tested this on two different computers running Fedora 13 (kernel versions tested listed below) Ran an yum update (standard Fedora repos only) on one to make sure I had the latest and greatest and still occurs.
