Hi there,

I've got an issue with mod_python. There is a script (index.py) wich is 
processed when I go to http://www.xyz.somewhere/ but when I reload
the page 3-4 times I'll receive the error below. It doesn't matter if the page 
is reloaded fast or slowly.
The only point that may be an problem (but I didn't think so) is a factory 
which should provide the classes for the modules (not the python-modules) of 
the site.

thanks for your help!!

mod_python: 3.3.1
python 2.4

The Factory:
class ContentFactory:
  def factory(self,className, *args):
    aClass = getattr(__import__(__name__), className)
    return apply(aClass, args)

The error-message:
