Comment 8 for bug 664533

Also seen in a recent featured Ubuntu Chinese edition: while selecting Spanish keyboard: only Camboya was listed. In consonance with comment 7, this happened when the user used the keyboard to select the distribution, and didn't happen when using the mouse.
The last process which was opened and hung was:
 /bin/sh /usr/lib/ubiquity/console-setup/console-setup.postinst configure
