The python backtrace is not the problem, the problem is the fact that
the C replication code returns NT_STATUS_INTERNAL_ERROR.  

As the schema handling improves, at some point we won't get to this:

Can't continue Schema load: didn't manage to convert any objects: all 
216 remaining of 3187 objects failed to convert
Join failed - cleaning up

Kamen has been working on this area, and while I will not promise what
others can do over the Christmas break, Kamen has been working on
exactly this kind of problem (inability to import 'custom' schema).
