The actual issue is in lp.archiveuploader.parse_tagfile_lines - it has introduce a limited number of corrupted values for SourcePackageRelease.dsc_binaries with a trailing '\n'.
I've created and tested an intermediate work-around that rstrips the dsc_binaries when creating the index file, which will give us a bit more time to solve the original issue properly.
