I am having the same problem on Karmic (Mythbuntu 9.10 more exactly).
The version numbers are slightly different but the issue is the same (the SMBFS package wants a Samba common 2:3.4.0-3ubuntu5 whilst a 2:3.4.0-3ubuntu5.1 is installed.
I only use the standard main, universe and multiverse.
I wonder if samba common was updated via some security update but that the other stuff like smbfs and smbclient was not (and perhaps if I had installed smbfs before the security update then it would have worked and got the correct library?).
