Syphon for QCのパッチがスクリーンセーバとして動かない(OS X 10.6)

2013.6.23 追記: こちらで議論されてる問題と類似のようで、bangnoise氏が添付しているSyphon.pluginを使うとエラー解消しました。

MacOSX10.6.8でSyphon for QCのクラインアントパッチをスクリーンセーバとして起動すると何も表示されない件。

どうやらスクリーンセーバエンジンでエラーになっている模様。
プラグインが10.6.8と相性が悪いみたい。試しに同じことを10.8.2で試したところ問題なく動いたので。

ちなみに10.8の場合、作成したスクリーンセーバは、/Library ではなく、ユーザホーム下のLibrary下に置いてやらないと、システム環境設定で認識されない、というちょっとした罠があるので注意。
