Thanks for that; this was invaluable information! After some analysis, it
appears that parted doesn't like the geometry of one of your partitions, and
therefore fails in a place where partman is not expecting it to fail. It's
possible that a newer version of parted might fix this, but it's too late to fix
that now.

I'll have a partman-base fix for you shortly; tomorrow's daily build will
include it.
