For the kwrite problem, changes in
kdelibs-4.4.0/kdelibs-4.4.0/kate/view/kateviewinternal.cpp seems to be culprit.

I think following patch is the right way to check what it should be.  As far as
I tested, it fixes the problem with uim.

   // if the input method event is text that should be inserted, call

-  if ( e->commitString().length() > 0 && doc()->typeChars( m_view,
e->commitString() ) ) {
+  if ( e->commitString().length() > 0 && !m_imPreeditRange &&
doc()->typeChars( m_view, e->commitString() ) ) {
     e->accept();
     return;
   }

But I'm not sure what the original code is intended, so please consult KDE
developer about this.
