[Bug 1167455] [NEW] Dead keys stop working fine in KDE apps after navigating through menu bar

[Jorge Rodríguez López]

Public bug reported:

Accented letters (dead keys) stop working fine in KDE apps after
navigating through menu bar's.

When typing in the text area of KDE applications, the keyboard (with
dead keys) work fine, but if you access the (classic) menu bar in the
application window, dead keys may stop working fine.

e.g. with English (US, international with dead keys) layout
  Press key "´" and "A", expected output= "á"
  output with ibus= "" (nothing)
  output with xim= "´a" (Dead keys are alive)
  
Exceptions:

- With widget Window Menubar no problem.
- In Rekonk, with menu system like Chrome, no problem.

Steps to follow:

In KDE desktop...

1º Check that you are using a keyboard layout with dead keys, if not, install and use one.
    System Settings > Input devices > keyboard > Layout > Configure layouts
    e.g. English (US, international with dead keys)

2º Open a kde app, (i.e. kate)

3º Write something to check that dead keys work well.
    In English, e.g. press "´" and "A" results in "á"

4º Access of the menu bar in the application window and scroll through
the options for 30 seconds or more.

5º If dead keys fail, change the focus (i.e. another window) and return
to kate, dead keys work again.

Testing:

Tested in different computers.
Tested in Debian, kubuntu (13.04, 12.10, 12.04), OpenSuse.

I apologize for my English.
