After that point, apache would segfault at starup, or indeed even at apache2ctl -t (after outputting "Syntax OK"). Simply disabling mod_ssl would get me back to a working config. This is all before I even changed the apache or RT configuration from the pre-SSL, working state; just the loading of mod_ssl seems to cause the segfault.

This looks like the same bug as #632129 (CCed), which Niko wasn't able
to reproduce.
As he suggested, stripping away other bits of Apache configuration
to see if the problem goes away would be one way forward.
