OK, But what is it? Does it contain any spaces or letters or punctuation 
characters?

Try separating out the line and then adding a try/except like so:

try:
    line = next_line(the_file)
    points = int(line)
except ValueError:
    print "Line causing error is: \n;", repr(line)
    raise

That way you will see exactly what causes the exception.
