Package: samba
Version: 3.0.24-6etch9

Hi! nmbd has crashed on a few occations at 06:25 AM (the same time
that cron.daily is run) and the the following message with subject
"Panic or segfault in Samba" was mailed to me:

> The Samba 'panic action' script, /usr/share/samba/panic-action,
> was called for PID 1185 (/usr/sbin/nmbd).
>
> This means there was a problem with the program, such as a segfault.
> Below is a backtrace for this process generated with gdb, which shows
