                    keyboard does not work.
           Product: kde
           Version: 4.7
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED

Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

Dead keys (circumflex and umlaut) of some French keyboard does not work. I use
a generic keyboard 99 keys, missing in the setup menu keyboards, and auto
detected as a 104-key.
The behavior is different depending on the application: it works correctly in
Firefox and Google Chrome, for example. In most KDE application, "ô" becomes "^
o". In some other applications it becomes "o" (libreOffice...). Yet xev returns
a correct information:

This bug seems persistent in years when seeking a solution on the web. But I've
never had with Mandriva, this symptom appears with Kubuntu.
