Bug#679738: libgtk-3-0: Windows out of focus while they're not

[游千岳]

I'm having the same problem with gtk3 terminal emulators (roxterm-gtk3
(2.6.5-1), sakura (3.0.4-2)). And gtk2 terminal emulators (roxterm-gtk2
(2.6.5-1), lxterminal (0.1.11-4)) are working fine.

This guy also had problems with gnome-terminal and gedit.

Here's how this problem occurs on my machine:
I'm using wmii window manager. I launch sakura, for example, switch to an
empty tag, and switch back. The sakura window get back focus, I can still
type, but the cursor never blinks. And other applications still think it not on
focus, I can't use ibus with it now.
To get focus really back, I can switch to an non-empty tag, then switch back,
the cursor starts blinking again, and ibus gets working.

libgtk-3-0 version: 3.4.2-2

Please fix this.
