Thank you for the work Jack, and sorry for the review delay. Do you want to SRU that change or is fine to upload to trusty? Could you also update the diff to add a new changelog entry? You can't just add a line to an existing changelog for an upload

Hi seb128, thanks for your comments. I think it's ok to upload this change, as well as other changes, to trusty. We will upgrade to 0.2.2 soon:).
