[Pkg-xfce-devel] Bug#760740: Bug#760740: lightdm leaves at-spi process behind after login

[Samuel Thibault]

Hello,

I'm afraid this won't get solved properly in time for Jessie.  I'd like
to propose the attached patch, which doesn't manage to kill at-spi
processes, but at least removes the reference to it from the root
AT_SPI_BUS property, thus clearing the way for the user session's own
at-spi process.  This would thus fix accessibility in xfce, lxde,
mate, and also fix qt-at-spi's grave bug #762672, which is essentially
due to qt-at-spi being given a non-working qt-at-spi reference in the
AT_SPI_BUS property.
