gnsync on notes with images

I couldn't find anything about the subject in the documentation.
Is this an unsupported feature?

This pull request on the old repository seems to solve the problem (or at least it did back then):

Yes, I pulled that commit into this repository on Feb 10, 2016 (4a8c30b), but I did not add any documentation.
