Kodi media player: 'previous' button doesn't work for TV

[florianj1]

Home Assistant release (hass --version): 0.60.0

Python release (python3 --version): Python 3.6.3

Component/platform: Hass.io installation on raspberry pi 3

Description of problem: I am running Kodi media center with VNSI plugin to watch television. Interacting with kodi works fine except form switching to the previous TV channel. Switching to the next channel works. Calling media_player.media_prevoius_track results to the exception give below and thus the channel doesn't change.

Expected: Switch to previous TV channel

Problem-relevant configuration.yaml entries and steps to reproduce:

media_player:
  - platform: kodi
    host: 1.2.3.4

Traceback (if applicable):

Traceback (most recent call last):

Additional info: If I change kodi.py from

@asyncio.coroutine
    def _goto(self, direction):
        """Handle for previous/next track."""
        players = yield from self._get_players()

        if players:
            if direction == 'previous':
                # First seek to position 0. Kodi goes to the beginning of the
                # current track if the current track is not at the beginning.
                yield from self.server.Player.Seek(players[0]['playerid'], 0)

            yield from self.server.Player.GoTo(
                players[0]['playerid'], direction)

to

@asyncio.coroutine
    def _goto(self, direction):
        """Handle for previous/next track."""
        players = yield from self._get_players()

        if players:
            yield from self.server.Player.GoTo(
                players[0]['playerid'], direction)

everything works as expected, since skipping to the beginning isn't supported for TV channels

I took some time, but now I am running home-assistant 0.66.1. The issue is still unsolved, since the code from my initial post wasn't changed. The Trace stays nearly the same:
