Actually, CSVFiles also breaks when I have more rows… Try this:
shell> cat > test3.csv

MethodError: Cannot `convert` an object of type Float64 to an object of type TextParse.StrRange
This may have arisen from a call to the constructor TextParse.StrRange(...),
since type constructors fall back to convert methods.ERROR: CSV parsing error in test3.csv at line 24 char 21:

column 5 is expected to be: TextParse.Field{Float64,TextParse.Numeric{Float64}}(<Float64>, true, true, false)
