TwitterLanguageDetection error

[chauff]

There is a bug in the TwitterLanguageDetection function. For a small number of accounts, the tweets are downloaded (and available on disk). But instead of the profile an error is returned:

null message="Error in nl.tudelft.rdfgears.rgl.function.imreal.TwitterLanguageDetector: no features in text"

(I guess it is something in one of the first tweets that makes the code fail).

Since I cannot upload files here, I added a xml file that yields this error to gist: https://gist.github.com/4223581
