Comment 1 for bug 1683914

Sorry, I am not very acquinted with git-build-recipe, but is this issue the same cause as the problem I experience when trying to build a debian upstream git with a recipe: https://code.launchpad.net/~maarten-fonville/+recipe/cargo-daily

and then hitting this error:
# git-build-recipe format 0.4 deb-version {debupstream}-0~{revtime}
