I've been have issues the current trunk and the SELinux patch(s) that were recently applied. I'm not 100% who's issue it is but it's clear that configuring with --without-selinux fixes the issue. I've captured a backtrace (and have the core file if more information is needed) and have attached that. The box I'm useing this on has a rather restrictive policy in place, so I'm not ruling out the possiblity that it just a configuration issue.
