I have 0.28 (0.28.1+fixes.20170903) installed on Ubuntu 16.04.3 and also
cannot get some metadata lookup tasks to work.  Movie lookups using tmdb.py
work but television show lookups using ttvdb.py have been failing for about
a week.

/usr/share/mythtv/metadata/Television/ttvdb.py -t
No handlers could be found for logger "MythTV.ttvdb.tvdb_exceptions"

I have previously installed requests_cache and a few other missing modules
using pip.  Can anyone here suggest anything else I can try to fix this,
short of reinstalling from scratch?
