Description

It happens here in lemill.net: http://lemill.net/content/language

It has something to do with line 1051 LargeSectionFolder?.py >>> b=int((8*log(b-mincount,2))/log(maxcount,2))

Well, the algorithm should actually be 

b=int((8*log(b-mincount,2))/log(maxcount-mincount,2))

And that can throw OverflowError? if either log gets a 0 to calculate. Also the latter log can produce a 0 which will cause a ZeroDivisionError?.

I suggest you fix the algorithm as shown above and put a try except around it for the two error types, in which case b=0.
