It turns out that the fix for bug 200803 broke selecting the Greek keyboard layout for d-i with gfxboot. It passes console-setup/layoutcode=us,gr on the kernel command line, which is all very well for casper's rather hacky keyboard selection code but causes console-setup itself to do completely the wrong thing. I ended up with XKBLAYOUT="" in /etc/default/console-setup, which is clearly wrong.
I will check whether the same goes for ubiquity installations; it's quite possible that it might, at least following the second round of fixes for bug 188492.
This is a regression from 7.10, and so release-critical (though I think not RC-critical).
Binary package hint: gfxboot- theme-ubuntu
