[Reproducible-builds] Bug#797759: diffoscope: tar.gz and tar.bz2 archives compared wrongly

[Michele Alessandrini]

Package: diffoscope
Version: 31
Severity: important


When comparing tar.gz or tar.bz2 archives containing text files, some of which different, the output is a binary diff. Perhaps it only applies decompression and compares the two tar files, instead of their contents?
