No matter what changes i make to file associations (actions) in the 'Applications' tab in Firefox, they're totally ignored.
For example, i set .wmv and .avi files to open with 'smplayer' but when i download a file and double-click on it (through the 'Downloads' window), it keeps opening with Totem player.
The default file associations through nautilus ('open with' tab) work fine, i.e. i've set smplayer as the default player and when i double-click a video file it open correctly.
I've tried to delete and recreate mimetypes.rdf but that didn't help.
Any ideas on what else should i check?
