Keyboard not working in gtk3 apps in Gnome 2?

Question

GTK+

Debian Wheezy has updated many of the applications included with Gnome to 3.0. Gnome itself is still 2.30.
So, the general design for gtk is not applied to them, but this is not terrible.
Interestingly, the keyboard does not work when working with such applications. For example, gnome-terminal or gnome calculator. That is, it is entered by copy-paste, but not from the keyboard.
On LOR, the topic was raised , but died out.
I managed to google one mention of a similar problem without solving it.
How to fix?
Solution found: disabling xneur. So it goes.

Answer 1

I advise you to rummage through the bourgeois Internet, I'm sure someone had a similar problem.

Answer 2

Is ibus-gtk3 worth it?
