When I press any input key (such as 'a' or '3' rather than any of the arrow keys, function keys, arrow keys, etc) and I have an item in the module selected gimp will crash. 

1. Edit -> Modules 
2. Select any item (you don't have to check or uncheck it)
3. Press an alphanumeric or symbolic key.
4. GIMP crashes.

The following is then output to the console: 
(gimp:8578): Gtk-CRITICAL **: gtk_list_store_get_value: assertion `VALID_ITER (iter, list_store)' failed

(gimp:8578): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.34.0/./gobject/gtype.c:4204: type id `0' is invalid
