Sometimes there is still some bug in Ubuntu after upgrade when opening Places Menus. It starts Totem, Rhythmbox or any other wrong application but not Nautilus.
The easy fix is described here: http://ubuntuforums.org/showpost.php?p=6079168&postcount=12
In summary, the best fix is to edit ~/.local/share/applications/mimeapps.list removing the offending .desktop entries against the inode/directory entry.
e.g. from:
inode/directory=userapp-baobab-OO53FU.desktop;nautilus-folder-handler.desktop;nautilus.desktop;userapp-nautilus-XXZ2JU.desktop;
to:
inode/directory=nautilus-folder-handler.desktop;
There is no need to go through all the places bookmarked changing the "open with" options.
