Bug#826319: devscripts: debdiff fails on diffing .changes with matching version but different package lists

[Andreas Beckmann]

Package: devscripts
Version: 2.16.4
Severity: normal

Hi,

I just tried to convert fakeroot to use debhelper. To see whether I
didn't miss something previously shipped, I wanted to debdiff against a
.changes with only the version bumped (to reduce noise), but no other
changes. That worked until I enabled dh_strip, which added -dbgsym debs
to the new .changes:

$ debdiff  ref/fakeroot_1.20.2-1.1_amd64.changes fakeroot_1.20.2-1.1_amd64.changes
debdiff: fatal error at line 456:
Can't read file: ref/fakeroot-dbgsym_1.20.2-1.1_amd64.deb

Hmm, there are no -dbgsym packages in ref/, why does debdiff try to load
them? It works fine with 

$ debdiff  fakeroot_1.20.2-1_amd64.changes fakeroot_1.20.2-1.1_amd64.changes 
[...]

where the old one doesn't have -dbgsym packages either, but has a
different version number.
