Fix usage of bare 'except'

flake8 reports:

  E722 do not use bare 'except'

Replace them with 'except Exception' per [1] which says:

  Bare except will catch exceptions you almost certainly don't want
  to catch, including KeyboardInterrupt (the user hitting Ctrl+C) and
  Python-raised errors like SystemExit

  If you don't have a specific exception you're expecting, at least
  except Exception, which is the base type for all "Regular" exceptions.
