Other than suggesting that you insert a space after the colon in the subject, I don't have any further comments on this patch. That's probably not a reason to resend, though.
As general commentary to any potential GSoC students reading this: do what you can to ease the review process. One way to do so is to supply commentary below the "---" line (or in the cover letter) explaining what changed in the present patch compared with the previous attempt. Bonus points for providing a reference to the previous version of the submission, like this [1].
