fwiw thunderbird works for me but I got the same error running evince 
(48, from testing) with latest gdk-puxbuf, (running on GNOME from 
unstable),

evince 49 (from unstable) works fine (but it's been ported to gtk4 so 
there are many changes that could explain it).

I'm available for anything that would help debugging this.
