Warning from QT5

[Jorge Carrión <shordi@xxxxxxxxx>]

For a few days now all my programs have issued this warning through the
console:
Qt: Session management error: None of the authentication protocols
specified are supported
I think they recently updated qt5 in Manjaro Unstable, which is the one I
use.
Everything works fine, I don't even think it's a bug, but...
