gnome-control-center crashed with SIGSEGV in gtk_tree_model_get_valist()

The sound-properties dialog (started via the sound menu or directly from gnome-control-center) crashes reproducibly when changing the "Play sound through" setting in the Output tab. After it crashed once, all subsequent attempts to start it fail, i.e. it crashes immediately on start.
A workaround is using pavucontrol to change the sound source, after this is done, gnome-control-center can also be started again.

When gnome-control-center crashes, it prints the following to the terminal:
Gtk-CRITICAL **: gtk_list_store_get_value: assertion `iter_is_valid (iter, list_store)' failed

GLib-GObject-WARNING **: /build/buildd/glib2.0-2.31.16/./gobject/gtype.c:4205: type id `0' is invalid

GLib-GObject-WARNING **: can't peek value table for type `<invalid>' which is not currently referenced
