What does the following error mean?

Traceback (most recent call last):
  File "convert_from.py", line 187, in <module>
  File "convert_from.py", line 181, in main
  File "convert_from.py", line 123, in process_profile
  File "libprs500\ebooks\lrf\web\profiles\__init__.pyo", line 92, in __init__

  File "libprs500\ebooks\lrf\web\profiles\__init__.pyo", line 159, in parse_feeds
ValueError: too many values to unpack

I get it when trying to process the following feed:

Thanks.
