[mod_python] QUERY_STRING and running a cgi script under mod_python

Hi,

I'm having a hard time getting a CGI script to run under mod_python. 
Basically the problem seems to be get variables aren't accessible using 
cgi.FieldStorage() under mod_python the way they are under plain old cgi.

I seriously doubt I'm the first one with this problem but I haven't 
found any solution.

os.environ['QUERY_STRING'] contains the correct query string so they 
aren't been stripped.

Is this documented somewhere? Any known workarounds?

Thanks
