I had a similar problem with structs some time ago. I nailed it down
to mixing up the order of members in the constructor argument list.
As Python does not check these, you can create a structure with anything
as contents and will then get a BAD_PARAM exception...

Try whether you can send back a structure you obtained from the
server...
