In http://qa-logs.debian.net/2020/09/26.fixfilepath/ you can find:
00cmp.fixfilepath.only-fails-with-fixfilepath.txt: that's the list of
packages that fail with fixfilepath, but don't fail without it.
00res.fixfilepath.txt: the full list of built packages
00cmp.fixfilepath.txt: the differences with a normal build
... and the logs for the packages listed in the first file.
Let me know if you need something else.
