I was a little early in posting the bt -- it seems that that there
must be an exception tree, or multiple exceptions -- I have several
successive cont for which I got a bt. This is all from a single
request.

Sometimes, between call_user_function and call_user_function_ex the
parameters like function_table are valid (function_table=0xa0a2350)
and sometimes they are not (function_table=0x0 or function_table=0x1).

I'm trying to attach the multiple bt for this, hopefully the list will allow...
