Directories kept opening with my Media Player :(

Since upgrading to GNOME 3 with Fedora 15, whenever I tried to open a folder or insert a USB key, Totem, my media player, would try to open it.  This had been quite annoying.  I tried to go to System Settings -> System Info to change the Default Application for folders, but the option wasn't available.

I thought there might be a GSetting for it, so I tried to modify the key 'autorun-x-content-start-app' for the schema 'org.gnome.desktop.media-handling', but to no avail.  Then, I tried looking for .desktop files, and found a stash in ~/.local/share/applications/.  I greped for 'totem' and found a relevant reference in 'mimeapps.list'.  Therein, I found a line:

inode/directory=gnome-nautilus-folder-handler.desktop;phatch.desktop;f-spot-import.desktop;totem.desktop;gthumb-importer.desktop;gthumb.desktop;

Given that yum says nothing provides the first .deskop in the list, and that I don't have the next two installed, it made sense that totem was being called.  I wonder where gnome-nautilus-folder-handler.desktop came from?

Anyway, I removed the line, and now all is well, and nautilus opens directories again.  Glee.
