Wrong package, this is in libconfig-model-dpkg-perl ...

And there's an interesting hint about changes in apt and a possible
way for a fix:

 | problem is:
 |   * don't hardcode /var/lib/dpkg/status as dir::state::status
 | in apt 1.3~pre3
 |
 | fix is adding:
 | Dir::State::Status "/var/lib/dpkg/status";
 | around line 160 in /usr/sbin/update-pepperflashplugin-nonfree


Hm.
/usr/share/perl5/Config/Model/Dpkg/Dependency.pm line 716.
is $apt_cache->get($pkg);
and $apt_cache is AptPkg::Cache->new

so maybe the problem is in libapt-pkg-perl? Or in the way it's used
here?


Cheers,
gregor
