Bug#669103: Scroll doesn't work properly anymore

[Mehdi Dogguy]

Package: libgtk-3-0:amd64
Version: 3.4.0-1
Severity: normal

Hi,

After upgrading to libgtk-3-0:amd64 (= 3.4.0-1), mouse scrolling
stopped working properly. It stopped completely working within
gnome-terminal, and was disfunctional in other gtk applications
(iceweasel, icedove, epiphany, ...).

Downgrading back to 3.2.3-1 made scrolling work again (using mouse
wheel or touchpad).

I'm not sure this is the same (though it seems to have same symptoms)
as #666921. So I preferred to file it in a new bugreport. Note that my
gnome-terminal *does* work with libvte-2.90-9 (= 1:0.30.1-4). I don't
have to upgrade vte to 0.32 to have scrolling working again in my
terminal.

FWIW, My downgrade aptitude session that brought scrolling back lists
the following packages:
