I had the same problem in kppp. Matthias E. advised me to simply remove
the X Error handler Bernd used to put into his apps. In your case it is
knotes_x_errhandler() in knotes.cpp. KApplication has its own handling
routine.

Matthias, could elaborate on this problem a bit further ? I know that X
asynchronous nature leads to problems but why didn't this problem occur
in KDE 1.x ? Isn't there a "clean" solution ? I *have* to activate the
handler again in kppp to catch a sudden X shutdown. Guess I'll simply
ignore the above error then.

Harri.
