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.
