The problem comes from XAUTHORITY.

[Antoine Martin]

"fix" by removing xauthority

[Antoine Martin]

Temporary fix merged in r22762.

I just don't understand why using a private XAUTHORITY started to fail recently.
Running the same commands from the command line succeeds.

[Antoine Martin]

r23180 removed the private xauth code.

This is not properly "fixed", but it works..
