The problem is here, I think.  Split in Python appears to return the
separator, so the '\n' characters are still there.  If that's the problem,
this should fix it.

if line == '\n':

At least, that's my suspicion, without testing.  (In Perl, the separators
are not returned by default, so if you came to Python from Perl, like me,
this is confusing.)
