I went:
dpkg --add-architecture i386
apt-get update
apt-get -u dist-upgrade
Saw this:

The following packages will be upgraded:
ia32-libs ia32-libs-gtk libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libglu1-mesa libxml2 libxml2-utils python-libxml2 unzip
Felt that was a bit too many packages (182 new i386 packages) to be installed so:
apt-get purge ia32-libs ia32-libs-gtk
For you this will get rid of more packages than you may want. Make a note.
For me skype is not installed as a deb so that's safe.
ldd `which skype`
Gives me a list of libs it uses, including missing, which led to:
apt-get install libqtgui4:i386 libc6-i686:i386
apt-get install libqt4-xml:i386
apt-get install libqt4-dbus:i386 libqt4-network:i386
apt-get install libxv1:i386
apt-get install libxss1:i386
This gives me 39 i386 packages. A -lot- less.
The thing with ia32-libs ia32-libs-gtk is that they contain lots of packages
within them and debian does not know which you /really/ need. Installing
the 182 just keeps things safe. Note the upgrade of ia32-libs ia32-libs-gtk. These
are 130 bytes in size installed. Down from 500MB (from memory). Effectively
the old libs get uninstalled.
It's a little bit of potential work if you want an optimised install but not
hard.
If you don't care you just upgrade and let Debian take care of it.
All in all, no biggie.
