I had a similar problem.  It seemed to me to be some kind of
interaction between encoders being imported by the C encode()
implementation and modules being imported by mod_python.
Unfortunately I could only look at it without our complicated build
environment so I can't say for sure.

A workaround turned out to be forcing the encoders to be loaded before
mod_python starts up.  You can do this by adding a line like this to
sitecustom.py:

  u'hello'.encode('koi8-r')
