TypeError encountered in Word_List and Word_Cloud modules

[michael-myers]

The wordlist and wordcloud modules are great, and they work for many of the Twitter users I've run them on, but they fail on my own username (@fristle) so I was wondering if there's a way to debug this.

Steps to reproduce the issue:

1. Launch birdwatcher and enter the initial configuration.
2. user add fristle
3. status fetch
4. use statuses/word_cloud
5. set DEST /home/mmyers/Desktop/wordcloud.png
6. run

Generating word cloud, patience please… failed TypeError: can’t convert nil into Float

If generating the plaintext word list, it seems that a common underlying error truncates the list to a single word. Did I maybe tweet a special character?
