xmls duplicated?

[solars]

Hi there, and first of all thanks for your nice library!

I came across the following issue: https://gist.github.com/1089280

As you can see in output, the xmlns element is duplicated, I guess thats a bug, but not sure if in premailer or nokogiri.

In addition, one more side question, just out of interest: I noticed that with 1.6.x I had the problem that premailer added display:none to a lot of elements, and I did not really understand why - now with 1.7.1 this seems to be gone, was this a known issue?

Thank you, Christoph

I've noticed the same issue and still happening.
