winbind crashes..

[Collen]

Hi,

I'm trying to make samba 3.6.3 work against samba 4 (git pull)
in the past i had encountered some problems with wbinfo
but that is solved.
now a day i can enumerate users/groups with wbinfo again.
it is a migration from s3 (passdb.tdb) with samba-tool.
no errors encountered while upgrading to s4.

the problem i (still) encounter is with getent passwd and group

winbind just crashes with a backtrace on samba 3.6.3
i'm not sure where to debug, on s3 side or s4 side

attached a sniped dump from 363 with db level 50.
