Comment 120 for bug 260492

The probem exists for me in Maverick.

If I have gnome-mplayer installed, *and* I have at least once opened System->Preferences->Preferred Applications (without changing anything there!) "Places" start being opened by mplayer instead of nautilus.

Presumably (?) "Preferred applications" creates ".local/share/applications/mimeapps.list" file, and it has "inode/directory" with "bad" order of entries.

Obvioulsy editing this file and making "nautilus-folder-handler.desktop" the first (or only) entry in this line reverts things to norm, but this should not happen in the first place.
