[Pkg-samba-maint] Bug#410823: samba: smbd segfaults during startup

[Fabien COUTANT]

Package: samba
Version: 3.0.24-2
Severity: grave
Justification: renders package unusable

After upgrading samba (3.0.23d-4) to 3.0.24-2, smbd doesn't restart !
I receive a "Panic or segfault in Samba" mail, and /var/log/samba/log.smbd
contains at the end:

My configuration was perfectly working with previous version.  I'm now
reverting to previous version because I *need* something working.
Sadly, Debian mirrors don't keep the previous version in this case of
harmful upgrade, but by chance I did burn some binary DVDs recently.
