I had this problem with e.g. Nautilus vs Baobab on directories. Apparently the right solution is to install a desktop-specific package that manually does "tie-breaking" for MIME types that have multiple handlers. See 96d36f385cb1de83f95dd0404dc2166d6f877389. You might try just installing gnome-default-applications, or we might have a similar package. Andy
