gnome-panel and nautilus 1:2.29.92.1-0ubuntu3 are fixed and on archive.ubuntu.com. Upgrading to those will restore desktop functionality.
To temporarily recover from a blank desktop so you can run the upgrade, press Ctrl+Alt+T to start a terminal, and run 'gnome-panel'.
[I'm currently grepping recent binaries to find anything else that needs to be rebuilt, so it may be a while before some other missing applications return.]
