[Evolution] KDE vs. Evolution -- Keyboard input fails

[Jonathan Ryshpan <jonrysh pacbell net>]

If evolution is started under KDE, a new composer window is opened, and
the message format is changed from "HTML" to "Plain Text"  then keyboard
input to the composer window becomes impossible.  Proper behavior can
sometimes be restored by closing the composer window, sometimes only by
closing evolution completely.  Sometimes mouse input to evolution also
becomes impossible.  This kind of behavior happens only under KDE, not
Gnome.  If evolution is started from a console, it reports no errors.

Has anyone on the list seen this?  There's one other report of a similar
error at:
        https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1007133
Could it be some kind of keyboard focus problem?

System configuration is:
        Fedora-17 (just installed today; all updates in)
        Evolution 3.4.1 (evolution-3.4.1-2.fc17.x86_64 RPM)
        4-processor x86_64 hardware

I had this problem using Fedora-16, and had hoped that it would go away
under Fedora-17; but it didn't.
