I have no clue how I was able to do this as I cannot reproduce condition either. I remember checking that /var/lib/binfmts/openjdk-6 was indeed removed, but not by me. I installed icedtea-gcjwebplugin for testing and afterwards removed installed dependencies one-by-one when this happened.
Maybe ignoring the missing binfmts file would be okay as otherwise this results uninstallable package.
