I've looked into it a bit more and discovered that the failing reason
was autopartitioning_failed, which belongs to partman-auto-lvm's
perform_recipe_by_lvm. I've therefore added some debug as can be seen in
the attached patch.

The syslog got augmented accordingly with the final line in this
excerpt (which isn't much but better than before):

[ Except for the stupid log function name and logger tag, it might be
handy to merge such a patch into partman-auto-lvm to ease further
debugging; comments welcome. ]

I'll stop here for tonight because it's already past 3am, but I guess
that something changed in parted between 3.1 and 3.2 that might have led
the partman-server thing (that the various partman-* seem to be using)
to behave differently?

Mraw,
KiBi.
