[Reproducible-builds] Bug#779391: debbindiff: crashes when comparing .changes files for two versions of the same source package

[Paul Wise]

Package: debbindiff
Version: 9
Severity: wishlist

When I compare two .changes files from different versions of the same
source package, I get a crash. I would like to use debbindiff before
doing uploads to ensure that the changes to the package are good. I
already use debdiff to check the debs but would like to use debbindiff.
Below are a list of commands that can be used to reproduce this issue.

I guess the cause is that the file lists between the two packages do not
match and the solution would be to compare the file lists and map the
different versions of the binary packages to each other.
