Bug#239247: apt seems to pin all versions indiscriminately

[Frederic Briere <fbriere@fbriere.net>]

Package: apt
Version: 0.5.24
Severity: normal

I'm trying to prevent Christian Marillat's non-free unace package from
overriding the Debian package:

  Package: unace
  Pin: version 2.20*
  Pin-Priority: 49

I tried many variations of version, origin and release, to no avail:

  [fbriere] toroia:~ $ apt-show-versions unace
  unace/unstable upgradeable from 1.2b-1 to 2.20-0.0

Here's the output of apt-cache policy:

  unace:
    Installed: 1.2b-1
    Candidate: 2.20-0.0
    Package Pin: 2.20-0.0
    Version Table:
       2.20-0.0 49
          500 ftp://ftp.nerim.net unstable/main Packages
   *** 1.2b-1 49
          500 http://http.us.debian.org unstable/main Packages
          100 /var/lib/dpkg/status
       1.2b-0fbriere.4 49
          500 http://www.fbriere.net ./ Packages

All version appear to be pinned at 49, instead of only 2.20-0.0.
