[Antonio Ospite]

Package: libconfig-model-dpkg-perl
Version: 2.085
Severity: normal

Dear Maintainer,

when I run "cme update dpkg-copyright" in the davmail package I get some
messages like these:

-----------------------------------------------------------------------
$ cme update dpkg-copyright
cme: using Dpkg::Copyright model

By looking at the resulting debian/copyright file it looks like
Dpkg::Copyright tried to parse some binary files too:


-----------------------------------------------------------------------
...
Files: src/icon/*
Copyright: ›iÿ3gΔ; / z¿†>)çyñ]‘ïûÀ^”´;;/ / zxÜ»Ê“+õ3º
$InÉò++¼`ôú©¦»J#Y‰0
È-d~X„Rµg³Ïùma­ ~¦Ús|ô / lˇØÁ$?ñ˜È³ÿSné%SL
License: GPL-2+
...
-----------------------------------------------------------------------

The issue can be reproduced with these commands:

  $ git clone https://anonscm.debian.org/git/pkg-java/davmail.git
  $ cd davmail/
  $ cme update dpkg-copyright

Thanks,
   Antonio
