Summary: bug in idna-encoding-module

Initial Comment:
in /usr/lib/python2.3/encodings/idna.py, line 175 it goes:
lables = input.split('.')
which causes the interpreter to stop executing the
program, but by changing it to
labels = dots.split(input)
everything's fine ;)

This is now fixed in idna.py 1.4 and 1.2.12.2, by converting input to a 
string object. I leave this open to find out why there is a buffer object in 
the first place.

I can't see any problem in the code. The invocation of unicode() is 
correct - we just look for the exception that call may raise.

Rumpeltux, can you please report the exact input and exception you get?

Martin, it looks like line 174: unicode(input, "ascii")
should be input = unicode(input, "ascii").
I'm not sure what's supposed to happenning here, but it
looks like the if/else code block may be able to be
rewritten as:

if not isinstance(input, unicode):
    input = unicode(input, "ascii")
labels = dots.split(input)
