E.g. going to fonts:/// in nautilus reveals a number of font formats are not correctly recognized.
A patch to improve the situation for duplicate globs (as in the fonts example) can be found here: http://lists.freedesktop.org/archives/xdg/2005-October/007434.html A simple testsuite for shared-mime-info is beginning to take shape on my machine.
Duplicate globs patch got applied and is in rawhide. The test suite sits in fd.o bugzilla somewhere
See https://bugs.freedesktop.org/show_bug.cgi?id=5210
Since the patch got applied in rawhide and the testsuite stuff is in upstream bugzilla, I'm closing this upstream. Hope that's okay.
No, please leave it open for now.
Moving this to devel release.
The test suite got committed upstream, closing.
