The files are owned by the domain administrators group.  Winbind doesn't
know how to make up a 'user' record for that group yet.

Can you please try to get a gdb backtrace, or better still run 'samba'
under valgrind?  We would very much like to fix that. 

You could also file these details in a bug, if we don't sort it out
quickly.
