It may be related to a known bug in mod_python. See:


This is fixed in mod_python 3.2.

Suggest you try mod_python 3.2 beta.

Can someone here post how to get 3.2 beta from subversion of last beta snapshot
tarball. I don't have all my links handy to cut and paste.

Issue can't really be purused until you can ascertain that it is still a problem with 3.2.
Would at least need to know whether you mix use of apache.import_module() and
"import" statement for the same Python module/package which has been the source
of this particular issue in the past.
