Package: samba
Version: 2:3.3.3-1
Severity: normal
Over the last couple weeks I have received about twenty mails telling me that
Samba segfaulted. They all have the following backtrace:

I can't think of anything I'm doing to trigger this, it just seems to happen
occasionally. I haven't noticed any interruption in service to clients.
The server itself is just my laptop, sharing a few files to other client
machines. Nothing heavy.
