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.

This bug for some occasional segaults is around for a while. It was
reported against a version (3.3.4) which with had transiently in
Debian and maybe related to Vista clients.
I so highly suspect that there is zero chance for us to investigate it
now that I prefer closing it.
(one might think that the bug has valuable information for some
investigation to be done but, frankly, not 2 years after the bug was
reported and not with a version of samba that is two major releases
prior to the current one.
Please reopen another bug if such errors and segfaults pop again, with
the current version of samba in at least squeeze.
