Wubi missing i386 architecture

Just a quick post to highlight a bug in the disk images for Wubi 64-bit. It's supposed to have multiarch support so you can install 32-bit packages, but it's missing. I don't know a lot about it - other than to notice the bug report and a bunch of user support requests, but it looks like the way around it is to run:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs

Note that this only affects users who installed 64-bit Ubuntu by running wubi.exe standalone. If you installed from the ISO or installed any other flavour e.g. Kubuntu, Edubuntu, Lubuntu, Xubuntu, Mythbuntu it wouldn't apply.
