Description Alban Browaeys 2015-11-19 11:18:15 UTC 
https://git.gnome.org/browse/gtk+/commit/?id=e25ea62f22ce0bbb7175f93c07de5cab773778a7
introduced a crash . That is when impl->transient_for is NULL , get_popup_parent do the "do" before the window is null test. That is window->impl is dereferenced while winodw is NULL.

It might well be that a plain while would do fix the issue. I report now , but no fix was tested on my side yet. I am using debian gtk+ 3.18.5-1


the  impl->hint is:
gtk.gdk.WINDOW_TYPE_HINT_DROPDOWN_MENU
