I came back after a month long vacation to check out my parents computer, only to realize that the bookmarks (e.g. Places → Downloads) opened up VLC. To try and fix this, I uninstalled VLC. But when I open those bookmarks, the browser (Firefox) launches instead.
How do I fix this and get Nautilus to launch?
PS. I'm using docky, and opening mounts from docky also has the same behavior.
