This is very strange.
I had have the some problem.
I have seen that if the Zope generate a lot of empty lines at the begining 
I receive this error.

the idea is to dont have too many empty lines at the begining of the output,
(I have no idea how many)

try to write something at the begining of the output doc.
I use someting like "Content-type:...."

PS: My English is not so good, 
maybe you dont understood what I want to say
