[Samba] PANIC: internal error (lib/fault.c:fault_report)

[TBrown at neurology.ahsc.arizona.edu]

I'm running Samba 3.0.1 in an ADS configuration (SuSE Linux 9.0). Whenever
I attempt to access the Samba server via Windows networking (network
places, etc.) I get the following error report in the smb.log. There wasn't
much available on the lists or the web on this...

 Any help is appreciated.

Similarly, I am getting additional errors that may be related:
