Binary package hint: samba

Running 6.06 LTS, I did a routine update/upgrade and now Samba will no longer start. The system sends this email:

--------------------------------------------------------------------------------

The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for pid 8377 (/usr/sbin/nmbd).

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 Ubuntu.
For information about the procedure for submitting bug reports, please
