Oh. That's surprising indeed. You can see an example failure at
https://crossqa.debian.net/src/gnustep-gui. Could it be that you pass
-nc or --no-pre-clean to dpkg-buildpackage somehow? When building with
sbuild, this likely makes sense as it slightly speeds up a build where
cleaning is not necessary. It's not the sbuild default however.

Thank you very much for having put in this effort. I was quite surprised
to that it just worked after fixing the cleaning and now I know why.
