Comment (by jasonliu--):

 I can't figure out what's causing the crash on launch. I'm going to go
 ahead and submit the PR, because it does resolve this current ticket's
 problem with not being to use {{{gtk-mac-integration-gtk3}}}. The crashing
 issue will probably need to be resolved in a different PR or Trac ticket.
