Comment 15 for bug 316959

Removing the code as in comment #9 removes the "Music" entry from the upper section. I can't determine where the list in the lower section is generated, although the documentation (http://developer.gnome.org/gtk/2.24/GtkFileChooser.html#GtkFileChooser.description) suggests it can come from "various sources". Perhaps somebody who understands Gnome better can find it. Unless we can determine at runtime that there is a duplicate entry, it may happen that bluntly removing the code actually removes the only copy of that entry.
