Comment:

 Oh, it looks like mime.get_mime_parents() is actually already using
 list_parents(). I think the real problem is the annotation on
 xdg_mime_list_parents. It should be transfer container, not transfer full.
 In fact that function duplicates only the array, not the strings it
 contains. The following fixes the issue for me

 - * Return value: (array zero-terminated=1) (transfer full):
 + * Return value: (transfer container):

 At least it fixes mime.get_mime_parents("text/xml"), which is crashing
 without that change for me (after running it a couple of times).
