In Amarok's script manager window, if no text is entered in the search/filter field, Amarok consumes 100% CPU. As long as some text is entered, Amarok becomes responsive again.
The search/filter field has focus when the window is opened instead of showing "enter terms to filter" (or something like that, I don't have English labels). I think it shouldn't have.
