I think I _may_ know what the problem is.

I have installed mod_python on my laptop with no problems, very easy
(once I actually read the instructions ;), anyway needed this on one
of the servers, so I asked my sysadmin to install. 

This turned out to be harder than I would have expected, we started 
with apache-ssl and couldn't get the thing working, kept segfaulting.

I said maybe it is a conflict with ssl extensions so we uninstalled 
acpache-ssl and installed apache standard, tried same thing happened.

After much swearing and cursing it turns out that the position of 
mod_python in the LoadModule section is very important.

By placing mod_python as the first Module imported things are good and
work fine, having mod_python as the last module to load causes segfault.

</boring story>

So the moral is:

make sure you load mod_python before other modules.

Gregory: Is this an expected problem? Should I patch the docs? 
(I don't think I have the time or ability to patch the code ;)
