Maybe the module is shot down when the thread is still running. And that 
would definetly result in a segfault. I believe  you should, do a 
vlc_thread_ready(p_this) in the FontBuilder thread and a 
vlc_object_attach(). And you should definitely do a clean up of the 
thread in the error path.

I would be glad if you could take a look at that.
