Manual Disk Setup doesn't work with LUKS ("physical volume for encryption")

[Malte S. Stretz]

When installing Kubuntu 15.10 you can select Manual Partitioning/Disk Setup. In the following dialog (cf. attached screenshot) you can select a partition type "physical volume for encryption". But after that there's no additional disk space popping up for further partitioning like it did before (admittedly I last installed Kubuntu on Karmic).
