Any non-empty file that ends in ".json" causes a segfault. It doesn't 
even have to be valid json.

Yes! I've attached a minimal version of freedesktop.org.xml that causes 
a segfault. It seems it has something to do with the interaction between 
multiple mime-type definitions, since the problem goes away after 
removing a single json or javascript related mime-type.

Best,
