I actually just figured out what was wrong the other day. For some reason,
/var/lib/dpkg/available had gotten damaged, which caused dpkg to segfault. A
quick 'dselect update' fixed that problem.

Of course, that doesn't take away from the fact that dpkg really shouldn't
segfault on a corrupt database, but that's another issue.

Thank you for your efforts!

If you can provide a copy of the corrupt database then the we can fix
the bug.

Ian.

dd if=/dev/zero of=/var/lib/dpg/available bs=1k count=16792

I was running on an XFS filesystem, and with unclean shutdowns, it has the
tendency to overwrite the contents of files with 0x0. Hardly seen it since
I've switched to Ubuntu, btw!
