The Samba 'panic action' script, /usr/share/samba/panic-action,

Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occurred.
If the problem persists, you are encouraged to first install the
samba-dbg package which contains the debugging symbols for samba
binaries. Then submit the provided information as a bug report to Debian.

Other things of note:-
What was happening at the time of the segfault is unknown.
I do have a backup script which uses smbmount to mount a Windows XP share,
backs up the mail folders and then unmounts the share.
This little script seems to leave multiple mount entries all from the
Windows box & share to the same mount point.
I have tried to duplicate this unsuccessfully but I've only tried very
briefly.
If log.nmbd is required please ask, I haven't restarted samba since this
crash.

According to the samba-common postinst, this line should have already been
corrected automatically if:
- you were upgrading from a version before 3.0.23b-2
- you said "yes" to letting samba manage smb.conf (default)
The upgrade code appears to handle cases both with and without the comma.
I'm afraid we've done everything we can here to support automatic upgrades.
Chris, to fix your problem change the "passdb backend" line in smb.conf to
list only "tdbsam".
