Hi Mannheim,
are you sure this is caused by problems with missing root persmissions?
In my experience, when gdm this bug does not appear (e.g. cifs mounts

Also present in hardy. pam_mount can't unmount on logout:

pam_mount(mount.c:104) umount errors:
The login-count bug mentioned in comment 1 is also a symptom of the
early-priv-dropping problem. When pam_mount decreases the login count to
0, it tries to remove the /var/run/pam_mount/$USER file, but can't as it
doesn't have the privileges to do so. This results in a stale login
count file.
