I don't see the relationshup between PPTP and the httpproxy segfault in this case. Can you please tell me how and why they are related

Hi utm_kid,

i'm currently investigating the segfaults. It seems like the proxy crashes with a memory corruption when trying to connect to a remote SSL Server. Do you know if the proxy crashes when you're browsing to a specific URL?

That's just a coincidence - the proxy crashed also on other times. It crashes in a function
which frees the X509 certificate of the remote server, so it seems somehow related to surfing to a HTTPS URI.

Hi utm_kid,

i've enabled debugging on your Box. So please ignore the tons of messages appearing in /var/log/http.log.

You can switch it off - i captured the log output. I'll try to reproduce the issue here.
