It's the host name that starts with a dot that makes it fails:
py> u".wikipedia.org".encode("idna")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "encodings/idna.py", line 163, in encode
File "encodings/idna.py", line 72, in ToASCII
UnicodeError: label too long
py> u"wikipedia.org".encode("idna")
'wikipedia.org'
The exception is certainly misleading; I'll have to find out
whether there is a bug beyond that (i.e. whether host names
with empty labels should be accepted).
