IBus input with TDE applications

Dear TDE users, is there a way to use IBus as the input method for TDE applications? I have installed and configured IBus on my system. It works fine with GTK and QT4 applications but I can't get it to work with TDE applications (which, I believe are QT3 applications). So for example, I can input japanese hiragana or korean hangul in Firefox or Libre Office, but I can't do the same in KMail. All help appreciated.
