Bug#809322: mpv: Complains about missing xdg-screensaver, which is installed

[Ralf Jung]

Package: mpv
Version: 0.12.0-1
Severity: normal

Dear Maintainer,

My MPV config file is

  # Use opengl video output by default.
  vo=opengl-hq

When I open a network stream (and probably also for local files), I get an error

  [vo/opengl-hq/x11] Disabling screensaver failed (4). Make sure the xdg-screensaver script is installed.

However, xdg-screensaver *is* installed:

  $ which xdg-screensaver
  /usr/bin/xdg-screensaver

Kind regards,
Ralf
