Interesting. Then this might really be a bug. There was a change in Python 
2.6.5 that broke universal newline handling for the codecs module, this 
might hit here.

However, according to what the OP described, the cr/lf characters turn up 
correctly now, so ISTM that it's the plain '\n' line ending that needs fixing.
