I've tried that too and had absolutely no problems, neither using guided
partitioning for the second disk, nor using manual partitioning. The LVs
already present on the first disk were correctly detected and I could set
up LVM VG and LVs on the second disk alongside them without any problems.
I have not tried encrypted LVM, but I don't see how that would make a
difference.

"This is where is crashed" is not very specific. Please describe the
excact steps you performed after starting the partitioner and indicate
when exactly the crash happened.

I don't see any crash in the first syslog, at most a "hang" (from looking
at the output from 'ps'. And I think that hang may already be fixed in
current daily built images, although it happened in a very specific
situation that I do not find in your description.
To trace this issue correctly we'll need two things (if you can still
reproduce it):
- a detailed and exact description of your actions from the start of
partitioning
- full debug output from partman; you can get that by adding a line
'set -x' in /lib/partman/lib/base.sh
One cause of the problem could be inconsistent traces of LVM metadata on
your disks from previous installs.
