(Bug about grandr, not xrandr, but grandr was not in the list... I hope this is the right place?:))

When clicking on the screen icon in the left of grandr, it crashes, and I see this as output on my terminal:

(grandr:13206): Gtk-CRITICAL **: gtk_list_store_get_value: assertion `VALID_ITER (iter, list_store)' failed

(grandr:13206): GLib-GObject-WARNING **: gtype.c:3339: type id `0' is invalid

(grandr:13206): GLib-GObject-WARNING **: can't peek value table for type `' which is not currently referenced Segmentation fault (core dumped)

Running gdb /usr/bin/grandr core gives this: [...] Core was generated by `grandr'. Program terminated with signal 11, Segmentation fault.
