Bug#522898: /usr/lib/libgio-2.0.so.0: Default file associations not used

[Sam Morris]

Package: libglib2.0-0
Version: 2.20.0-2
Severity: normal
File: /usr/lib/libgio-2.0.so.0

I've recently noticed that opening files from nautilus is using the wrong
programs. For instance, movies with VLC, mp3 files with mplayer.

Previously these files were handled both handled by totem.

Something seems to have happened to cause nautilus (gio?) to no longer
use the default file associations; since I have not told nautilus to do
otherwise, I guess it falls back to any old handler for the file.

I'd like to re-introduce the system-wide default applications, because I think
totem is a better default for movie files than VLC. But I'm not sure what has
changed or where to look...
