Simply put: no sane window manager will pass focus to KWallet if it 
doesn't have a window which it can be associated with.

This is the reason why KWallet opens behind (!) other windows and 
unfocused in Plasma when Akonadi tries to interact with it.

So at least in reality allowing 0 is not correct.
