Details:

The lastscrape script died two times when I tried to import my last.fm data.
It appears that that was due to last.fm's server responses because it
succeeded in the end.

The first attempt quit with a "connection refused" error after less than two
minutes. (the traceback isn't in my terminal's history any more..)

The second attempt died with the following:

Traceback (most recent call last):
  File "./lastscrape.py", line 70, in <module>
    sys.exit(main(*sys.argv))
  File "./lastscrape.py", line 61, in main
    for artist, track, timestamp in fetch_tracks(args[1]):
  File "./lastscrape.py", line 47, in fetch_tracks
    for artist, track, timestamp in tracks:
  File "./lastscrape.py", line 15, in parse_page
    for row in soup.find('table', 'candyStriped tracklist').findAll('tr'):
AttributeError: 'NoneType' object has no attribute 'findAll'


It was agreed on IRC that it's probably due to the lastfm servers but for
usability it would be nice to have an improvement in ways of error reporting
and error resilience.

Thanks.
