Hmm, this has nothing to do with libsmbclient, rather smbfs

Bug #264943 in Launchpad, for Ubuntu 8.10, seems similar to this one.

I'm not entirely sure of this, though. That needs investigation and
re-reading that bug (which has a very long log and for which fixes are
already in 3.2.6, IIRC).

I prefer using the "important" severity here, to still allow the
3.2.5-2 packages to enter testing (we have enough good reasons for
this). Please don't re-upgrade the bug severity too early.
