Ok, I tracked this down ... I'm using lighttpd as a FastCGI front end and it doesn't set SCRIPT_URI environment. So the line 1123 in rgw/rgw_rest.cc : s->script_uri = s->env->get("SCRIPT_URI"); Tries to assign NULL to s->script_uri which crashes with the particularly unhelpful stack trace I pasted above ...
