Bug Description

Expected: Installer to complete "installing base system".
Actual: Ubiquity hangs toward the end of the install.

'top' shows jockey-text at 100% CPU usage. Tailing the logs doesn't provide any insight. Will try this again with ubiquity in debug mode ...

This is ubuntu-oneiric-desktop-amd64+mac.iso on a MacBookPro6,2

The installer is running in German, but that may not be relevant.

  sudo killall jockey-text
allows the installation to continue to completion. The system is bootable and usable after that.

Looking at the syslog it may be relevant, that this is a German installation.
I see:

Sep 20 23:07:17 ubuntu ubiquity: Bitte 'j' oder 'n' eingeben und Enter drücken
Sep 20 21:07:18 ubiquity: last message repeated 78 times

Maybe someone somewhere is passing a non-localized 'y' for 'yes' and someone else is expecting a localized 'j' (Ja for yes). Attaching syslog and debug log from ubiquity. This should have more info that the previous logs.

        return False

Looks like this always asks for confirmation regardless?
