I haven't looked too deep into this, but it doesn't happen when you call
iter_paragraphs with shared_storage=False.  If you still wish to use
apt_pkg to parse the Packages file, you can work around this issue for
now by making a copy of each paragraph, e.g. instead of

  pkglist[k] = pkg

do something like

  pkglist[k] = debian_bundle.deb822.Packages(pkg)

I'll try to see if it's possible to keep track of "old" apt_pkg-backed
objects without explicitly making copies, but I suspect that's a price
we pay for the fast parsing...

Thanks for the report!
