Bug#848623: mate-power-manager now needs to be run as root

Package: mate-power-manager
Version: 1.16.0-1

I recently updated my laptop, and since then, mate-power-manager does
not seem to work any more if I run it in my session.  See transcript

If I run it in `su -' it works (at least to set the brightness),
although I think it was the actual mate-power-manager process that put
an icon in my tray, and now that doesn't appear any more (I presume
because it has no access to my X session any more).

In this configuration (running it in `su -'), I do get notifications 

I'm running:
  sysvinit as pid 1
  vtwm as my window manager
  trayer to hold my tray icons etc.

I'm afraid I don't really know how all this stuff is supposed to work.
I suspect I may be filing this bug against the wrong package.
xfce4-power-manager (which I also tried) seems to have similar

Hints as to where to look (or reassignment of this bug) would be very
