What are we going to do about the broken modifiers?

[Christoph Wickert]

Recent gtk updates have changed the way modifiers are handled and
therefor broken a lot of applications.
      * ALT keys are broken in all gtk based terminals. There is a patch
        for vte available at
        https://bugzilla.redhat.com/show_bug.cgi?id=626792 but even
        though it works, it seems controversial.
      * xfwm4 has lost all keyboard shortcuts using CTRL. See bug
        https://bugzilla.redhat.com/show_bug.cgi?id=759478

Even if the old to handle modifiers may have been wrong, this change
should not have gone into a stable release, because it breaks a lot of
applications (at least gnome-terminal, Terminal, lilyterm, sakura,
termit, terminator, xfwm4) and violates the "Avoid changing the user
experience if at all possible" rule of our updates policy.

What are we going to do now? Revert the change in gtk or fix all
applications?
