Subject: [PATCH] Trying to fix KDE BUG#167982

The bug is caused by preedit string update events that were sent by
scim-bridge during the focus change sequence. Problems:

1) QInputContext::setFocusWidget() is called before focus_out()
2) Preedit string hide event is sent even if it wasn't displayed.

As a result, when the focus is switched in, the _target_ Kate widget
receives a preedit event, and trashes its selection.

This patch is an obvious stopgap measure that seems unlikely to cause
regression, but requires attention of people with better understanding
of the affected interfaces.
