Bug#812555: gnome-session-flashback (temporary) black screen

[Massimo Martelli]

I'm sorry I thought you meant THIS one: https://git.gnome.org/browse/at
-spi2-core/commit/bus?id=2a70ba6bf83a675664cda8f68f2d1e815612db53
That's the commented line I was talking about. Anyway tomorrow I'll
apply the patch and try again.
I really don't know what to say about it starting even if it's not
enabled, but I'm sure I'm not mistaken about it.
Anything else I can check to help you find the cause?
