Oh, thanks for letting me know and sorry for the trouble.
I should had read the docs more carefully. I have actually been using for a
long while the strip methods as I had described in the bug report. I was so
completely convinced about this that I didn't even thought about checking
again the docs.
I have to fix my code but I am happy nonetheless as I was kind of 'losing my
faith' in python after finding this.

Regards,
Alejandro
