Thank you @bkneff ! Can you direct this PR to origin/develop branch instead of master?

[bkneff]

I just changed the branch to develop.

@bkneff there were a ton of merge conflicts, I resolved them all, so as soon as the merge commit travis run succeeds we can get this merged.

This is a very old issue. We encourage you to check if this is still an issue in the latest release and if you find that this is still a problem, please feel free to open a new one.
