UnboundLocalError: local variable 'best' referenced before assignment

Thanks for creating this. I've tried the tool and for most courses it works. However for some I'm getting the error below. Any help is much appreciated.

Traceback (most recent call last):
  File "acloud-dl.py", line 213, in <module>
    main()
  File "acloud-dl.py", line 206, in main
    acloud.course_download(path=options.output, quality=options.quality)
  File "acloud-dl.py", line 126, in course_download
    lecture_best = lecture.get_quality(best_quality=lecture_best, streams=lecture_streams, requested=quality)
  File "/Users/piethein/Sites/acloud-dl/acloud/_shared.py", line 210, in get_quality
    if not best:
UnboundLocalError: local variable 'best' referenced before assignment
