This bug seems triggered by recent changes in parted, but is actually in
partman-lvm.

This last devices is created because update.d/lvm_sync_flag did not skip
crypto devices and did set the "lvm" flag on the "virtual" partition.
The result is that partman believes that the "virtual" (of type loop)
has been changed and apply these changes on commit.
It then gets everything wrong and create the _cryptp1 partition.
update.d/lvm_sync_flag previously partitions on RAID devices, but this
must also be done for partition on crypto devices. And actually, it
looks to me like we could skip every disk with partition type "loop"
from LVM flag settings.
The attached patch fixed the issue in my tests.

Skip devices of type "loop" in lvm_sync_flag
Device of type loop (e.g. RAID or crypto) do not handle flag setting
correctly. Previously, only LVM on /dev/md* partitions were skipped in
lvm_sync_flag. We now skip every devices with the partition type "loop"
to also skip crypto devices.
