Ah, I think I see the problem then.  We free the list returned by gdk_display_list_devices:

https://git.gnome.org/browse/perl-Gtk2/tree/xs/GdkDisplay.xs#n59

But its docs state that "[t]he list is statically allocated and should not be freed."

https://developer.gnome.org/gdk2/stable/GdkDisplay.html#gdk-display-list-devices

So the g_list_free call needs to be removed.
