Parse media urls with Addressable::URI

[jayeff]

When providing a media url with an unicode char the error URI::InvalidURIError: bad URI(is not URI?) is thrown. Using Addressable::URI.parse solves this issue.

This fix is similar to pull request #233 / issue #223 where the same error occurred and switching to Addressable solved the issue.

Looks great to me. I'll run the tests when I get home (since Travis is having problems) and if they pass (which they obviously should) get it merged in for 1.6!

Thanks.

To test this change you can throw a unicode char (eg \u2013) into the slate_logo url. Run the tests and you see the bad URI(is not URI?) error. Apply this change and it is replaced by another error :) - because this url is not stubbed.

Ps: I do have three failing test_users examples. Don't know why but this seems to be unrelated to my change (I have the same errors on a freshly cloned repository)

Odd, which version of Ruby are you running? All tests pass for me.

Merged, thanks!

I did run the test both with 1.9.3-p194 and 1.9.2-p290. Same errors with both versions. Don't know why but also didn't look closely.
