Hi all,
  Look here: http://bazaar.launchpad.net/~inkscape.dev/inkscape/experimental/changes
rev 13365 managed to 'rename' my earlier commit to include poppler in win64 build.

My recommendation to not waste too many brain cycles: don't merge. You can create you own branch, fine, just don't merge it in. Just create a separate trunk/experimental checkout and copy your changes in, then commit.

Whatever you think about better workflows, it is paramount to maintain a clean version history. And again and again, we have proven that we are not capable of maintaining a clean history by using bzr merge.

Thanks,
  Johan
