[Pkg-xfce-devel] Bug#644917: lightdm: (null) is passed as argument to /etc/X11/Xsession

Package: lightdm
Version: 1.0.3-1
Severity: minor

Dear Maintainer,

This occurs when upgrading lightdm from 1.0.2-1 to 1.0.3-1.
user-session is set to lightdm-xsession that should pass default
as argument to /etc/X11/Xsession, but "(null)" argument is passed.
This can be seen in xsession-errors:

Xsession: unable to launch "(null)" X session --- "(null)" not found;
falling back to default session.

This has no visible drawback except when x11-utils is installed.
In such case, xmessage exposes the error message and the user has
to acknowledge it before allowing the (default) session to be launched.

Best regards

Pascal Dormeau
