Can you avoid the merge commit up above? Your master has probably deviated with this repo, requiring the merge before your pull request bases correctly for this repository.

But, pull requests should never contain merge commits. Can you instead add the upstream remote:
git add remote upstream http://github.com/kleiram/transmission-php

fetch it's master:
git fetch upstream master

create a new branch, with upstream/master as the base:
git checkout upstream/master -b metadata-percent-complete

cherry pick your commit:
git cherry-pick e89b56f1ac8fb79db31594611a641658c502d4dd

And that should work, unless there's a merge conflict somehow address in the merge, just run your tests and see. If you plan to contribute often, you shouldn't merge to your master until upstream merges, then you won't have these merge commits.
