amber giving error on kodi startup

Recently I have been seeing the following error on kodi startup using the amber skin.
I tried reinstalling amber, but it did not help

kodi 16.1
ubuntu 16.04.1

07:04:36 T:139785371559680 ERROR: EXCEPTION Thrown (PythonToCppException) : –>Python callback/script returned the following error<–

Any help appreciated.
Thanks Derek.
