.. I'd actually believe this is a Gtk3 and/or GNOME bug?
What happens if you downgrade Gtk3 to 3.20.9-1 or so?
(http://snapshot.debian.org/package/gtk%2B3.0/3.20.9-1/#libgtk-3-0_3.20.9-1)
This report and #836531 (I think) started happening with the new Gtk, because
at least for #836531
[2016-08-20] libreoffice 1:5.2.0-2 MIGRATED to testing (Britney)
[2016-08-14] Accepted 1:5.2.0-2 in unstable (medium) (Rene Engelhard)
^ this happened before
[2016-08-30] Accepted 3.21.5-1 in unstable (low) (Andreas Henriksson)
^this and the report was from 2016-09-03....
Cc'ing #836531 and -gtk-gnome.

Rene
