Comment 4 for bug 505197

Bug 282756 is unrelated, even though it happens to have the same user-visible symptom.

While I can see a reason this might have broken, I haven't actually been able to reproduce it myself, so I'll need a little help. Could you please add debug-ubiquity as a boot parameter (you can edit boot parameters by pressing F6 then Escape at the CD boot menu), reproduce this bug, and attach /var/log/installer/debug to this bug report again? Thanks in advance.
