After looking at this for a while, I think the assertion failure in
fontconfig is a bug in fontconfig, but I don't have a simple example
that will cause the failure.
I checked in a few more changes that seem to fix the crashes for me.
For now, I'm skipping the cleanup function for gh_manager. I intend
to fix it properly but I haven't quite finished the change yet.
