Comment # 28 on bug 1186341 from Michael Gorse

I can't seem to reproduce this (is there something else that I need to do
before hitting control-space?) I looked through the gtk3 commit log and don't
see anything obviously relevant. I did find one X11 DnD-related commit:
https://gitlab.gnome.org/GNOME/gtk/commit/39db78470452cf0b1a7d1ee196de3f20eea85d33

I just created a package in home:mgorse:branches:GNOME:Factory with that commit
reverted if anyone would like to test it, although I don't really think that
that is the change that introduced it. Regardless, simply reverting it isn't
really the right thing to do, since it was introduced to fix another crash.
It might help for someone to git bisect the gtk3 changes between 2.24.27 and
2.24.29.
