I've put the contents of /var/lib/dpkg/status,
/var/backup/dpkg.status.0, and the corefile (probably /home/laz/core) up
at http://adam.lazur.org/tmp/221706.tar.gz

Moving /var/cache/apt/{src,}pkgcache.bin out of the way didn't make it
happen, and I'm able to "reliably" reproduce the segfault ATM.

Let me know if you want me to poke at other stuff or how I can aid in
debugging things.
