Still have not managed to simplify it. I have managed to set up a simple
proxy using a virtual host, but I have yet to figure out how to fake those
http options.
Interestingly, I could get a simple sample page translated back into
ISO-8859-1 in this setup. This at least tells me that my self build package
works _in principle_.

Thought I'd send you the output of the crash with Loglevel debug. Maybe that
already tells you something:

I'll continue to try to build a simple test case, but I have to figure a bit
more stuff out for that...
