Comment 10 Miloslav Metelka 2012-11-12 12:40:27 UTC 
I still think that this must be caused by an obsolete BeforeSaveTasks class (though I think I've increased spec/impl versions properly). Anyway I have added a safe fallback into CloneableEditorSupport to act like if save actions were not present.
