Nevermind. I found that the problem was simply that when I replaced rm with a shell script that executes rm $* -I to require confimation, this caused dpkg to fail when removing files. I'm not sure why this problem only affected xulrunner and no other packages I installed and removed, but I guess it required that rm be a binary file rather than a shell script, which isn't a bug.
