"502 Couldn't parse server headers"

Hello.

I have detected that my installed version of Polipo throws the message 
"502 Couldn't parse server headers" when I try to browse the website 
"http://richard-falken.com". The website works ok when I test it with a 
non-proxied web browser.

I have noticed the server response contains "Upgrade: h2c" when telneting 
to the web server. Maybe this http/2 mess is confusing the software?

My Polipo is version 1.1.1 running on OpenBSD 5.8 amd64.
