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
