Problem description:
CEC used to work and is not working anymore (see error above in kodi.log).
At startup of Kodi it briefly displays same message on screen and basically I can not use the Phillips Remote Control to navigate Kodi. Also in System Settings menu of Kodi, Input -> Peripherals settings is grayed out so not available anymore.
I have had this problem since a few weeks, but I did not have the time yet to dig into it until now.

How to reproduce:
The error message always pops up briefly when (re)starting Kodi.
What I already tried is reinstalling CEC support following this (found in another thread in the forum):
--
sudo apt-get update
dpkg -l | grep cec # this lists all cec packages

sudo dpkg -r --force-all cec-utils libcec libcec-dev libcec3:armhf python-libcec # unstall all cec packages
, ignore everything
sudo apt-get install -f # Should reinstall all cec packages
--
Unfortunately it does not fix the problem.
I googled the error message for any leads, but no success so far.
So right now I don't know what to do to get it fixed.
Any help would be appreciated..

Thanks.
