I do not have KDE around to confirm it, but that is probably because of KDE's clipboard manager. A clipboard manager can “steal” the CLIPBOARD selection from other clients, especially if they do not support the SAVE_TARGETS mechanism for clipboard managers. You can try to terminate/kill KDE's clipboard manager while you are doing your experiments with the CLIPBOARD selection. Or you can edit the code to use the PRIMARY selection instead, which clipboard managers (usually) do not mess with. -- Lucas de Sena.
