Could you run «dpkg --audit». And then send that output and a tarball
with some of the dpkg database files, generated like this:

  $ tar -caf dpkg-911822.tar.xz /var/lib/dpkg/{status,triggers,updates}

Take into account this might perhaps contain sensitive information, so
you might want to make sure before sending it to the BTS that it does
not, the BTS might even reject it if it's too big, or alternatively
send it directly to me.

Does, running just «dpkg --configure --pending» solve the issue?

Thanks,
Guillem
