The original post and your comment both make it sounds like the various premailer libraries all share a common core, but I don't think that is true. Does the python premailer have anything to do with premailer.dialect.ca? I don't think it does.
Several months ago, when I was using Zurb Ink to design some emails, the python premailer would choke on some of the responsive CSS. I had to switch to the ruby premailer gem to get things to work. It looks like the python premailer has since been updated, so perhaps it works now.
