What do you have in /var/lib/dpkg/alternatives/ ?
Please give the output of "ls -alR /var/lib/dpkg/alternatives/".
I suspect that you have an (unexpected) directory and that we should
modify kill_bad_alternatives() to skip non-files.

yep, that's correct.
i had a directory in there called "junk" containing corrupted files
that i moved in there (from a crash during a previous apt-get upgrade -
problems with the intel graphics driver a few months ago, the machine
would lock up whenever X was restarted). i had meant to delete that dir
after repairing the system but forgot to.
i deleted the directory and was able to upgrade dpkg with no problem.
your patch looks like a good thing to do anyway.
