[Pkg-samba-maint] Bug#556536: started over from scratch - same result

[Dale Schroeder]

I gave up trying to fix the existing systems and downgraded to stable.
Today, I took a test machine and reinstalled the entire system.  There 
were no improvements.
Winbind would panic at a "getent group" command every time.  getent 
passwd, wbinfo -u,
and wbinfo -g do not appear to cause this anomaly.

Output of the panic:
