Segfault with midgard.http = Off

[flack]

Moved here from #116. This happens unconditionally on all requests I make against this particular Apache vhost (another vhost on the same machine works normally):

Program received signal SIGSEGV, Segmentation fault.

This only happens when midgard.http is set to Off, but independently of whether xdebug is enabled or not. It might be a separate issues, but I really couldn't say
