unfortunately the mailing list doesn't appear to allow attachments...

perhaps try to copy the "draw:object" elment out of the non-working 
content.xml and send that inline, then we can have a look?

not only the math node must be in the math namespace but all of the 
descendants like "semantics" too - i think that's the most likely 
explanation: create every element with the namespace.
