I'd suggest that this is 'supported' in terms of the release criteria,
under the Final criterion "The installer must be able to create and
install to any workable partition layout using any file system offered
in a default installer configuration, LVM, software, hardware or BIOS
RAID, or combination of the above": we don't explicitly list encryption
there, but we probably should, and I'd read the intent of the criterion
as being that encryption should be covered. So, I'd say you could
propose your bug as a Final blocker.

As far as 'should there be a test case' - well, it's kind of a tricky
question: there are essentially unlimited permutations when it comes to
filesystem layout, and we can't have a test case for *every single one*,
especially not a test case that must be done for the release to proceed.
There'd be no harm at all in you drawing up a test case for this
scenario, but whether we should add it to the matrices and especially
whether we should mark it as Final (indicating it has to be completed
for the release to ship) is a more difficult question.
