An update. I had written here that I seemed to be affected by this bug too, but I remembered later that just before running the "Software Updater" gui tool I had enabled the "pre-released updates" update source. After the update the system wouldn't boot, and seemed totally hosed. But I had a backup of the root partition made with fsarchiver and so I was able to restore it. I did that, then just now tried disabling, then enebling one at a time, all of the sources and PPAs that I had been using---excpt for that "pre-released updates" source. The updates went without a hitch, and it seems all good. So in my case the bug report was seemingly a false alarm, and I just wanted to let y'all know.
