In my doctests, I get the following error under 2.5.
I'm on AMD64 in case that's of any interest.

Traceback (most recent call last):

This bug is caused by your custom doctest module. Doctest
monkeypatches linecache's getlines() function. It was
fixed in the standard library to support an aditional
argument, but it looks that lxml is still using the 2.4
version.

Argh! Sure.

I only saw "doctest" and "linecache" and didn't even notice
it was using the local file. No idea why it's there anyway.

Thanks! Great time to close this 'bug' ...
