[Bacula-users] Bacula-sd crashing on DVD-RW backup

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

Recently my Bacula-SD is crashing. The only change that I can remember
happening to the system is a kernel update a few weeks back.

I've attached the GDB traceback e-mail that I got from the system.
Hopefully somebody can find out what's causing the crash.
