As no one is interested to fix this bug I've added a
workaround to switch to the Athena/Xaw3d toolkit
instead of using GTK which is done by this scriplet:

  #!/bin/bash
  # Avoid trouble with maximize/minimize within KDE (bug #345669)
  #  -> under KWin emacs does not maximize in the correct way if
  #     GTK/GDK is used as toolkit.  After click on the maximize
  #     button emacs shrinks to fit to the current font which
  #     destroys the maximize state in KWin.
  # Avoid trouble with "iconic" state information (bug #342385)
  #  ->  under KWin emacs with GTK/GDK toolkit does not hold its
  #      "iconic" state if a desktop state is saved before logout
  #      and restored after login.
  toolkit=gtk
  KDE_FULL_SESSION=$(xprop -root KDE_FULL_SESSION 2>/dev/null)
  case "$KDE_FULL_SESSION" in
  *true*) toolkit=x11
  esac
  exec -a ${0} ${0}-${toolkit}
