Found how to reproduce the bug, and the cuase. [15:00] <d_ed> jtalk: ok, imagine you have the setting "open tabs in a new window' [15:00] <d_ed> you open window 1 [15:00] <d_ed> it gets the right action, things are good [15:00] <d_ed> you open window 2 [15:00] <d_ed> you get the action for the first window [15:00] <d_ed> things still work [15:00] <d_ed> you close window 1 [15:00] <d_ed> that KAction* is now deleted [15:00] <d_ed> you type in window 2.. crash
