Yes, this seems to kill the problem. I will remove the handlers
knotes_x_errhandler and knotes_xio_errhandler in a few minutes.

After removing the handlers I now sometimes get when opening a 
dialog box:

KDE detected X Error: BadMatch (invalid parameter attributes) 8
  Major opcode:  42

No more X error messages occur when I close the dialog box. Strange!
