Segfault when joined to an NT4 domain that has a trust to a Mixed Mode ADS 
with restrict anonymous set to 2

Here is the relevant portion of the log.winbindd. I'll attach a bt when I get 
some time (it's not on my side right now):

I'm pretty sure this has been fixed as part of all the
work that has gone on with winbindd.  I cannot reproduce 
it.  Neither enumerating trusted domains nor sequence numbers
causes any panics in the log.  Reopen this is you can still 
reproduce this bug against the current CVS code.

originally reported against 3.0.0beta1.  CLeaning out 
non-production release versions.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
