[mod_python] more info about the segfault bug

Patch below. That variable "ext" is not being initialized appearently (in the 
function python_handler in mod_python.c). So I suppose it's not passing the 
"if(req->filename)" test, and so the call to apr_pstrcat just passes garbage 
("ext") to the function. Perhaps we need an "else" safety clause, or 
something? I don't really know what's supposed to be happening there, but if 
someone does maybe this will help them find the problem.

I will continue to look into the problem, but I'm not all that familiar with 
writing apache modules.


Regards,

Note: patch is from distributed version to me new one. Disregard my previous 
patch, which implemented Bryan Mongeau's solution.
