+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.
