double unlock required to unlock the screen

[Jean-Baptiste Lallement]

I have to unlock the screen twice to unlock the screen.
On 1rst attempt I have a completely aubergine screen without any widget at all (no label, password field, buttons, ...)
Then I have to lock the screen and unlock it again to display the usual screen and be able to log in.
