Do we have full debug level logs for the broken install available?
cause I did some refactoring on partman-lvm and partman-crypto
together with new upstream releases of lvm2, crypto, kernel.... there
are plenty of things that could have gone wrong.
Also just recently in ubuntu this upload was made:

To fix a very nasty:
https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1206235
Not sure if debian is also affected, and whether it's related at all.
