[Bug 1093223] [NEW] Panic or segfault in Samba

[Christopher Nighswonger]

Public bug reported:

Ubuntu 10.04.4 LTS

samba:
  Installed: 2:3.4.7~dfsg-1ubuntu3.10


Samba seems to segfault at random intervals for no apparent (to me) reason. Below is a backtrace.

I'm really not sure what to say beyond this. If someone will let me
know, I'll be glad to provide whatever other info I can.
