Public bug reported:

Got the following recipe for a one disk /boot + LVM setup (2 partitions, 2nd 
one is PV for VG, 3-4 LVs):

When I have a disk < ~24GB partman fails with "available disk space (...) too 
small for expert recipe (24320)". the last number indicates that partman 
calculates the total size of the recipe by adding all minimal sizes together 
(256+12032+2048+5120+4864+0). but since I'm using LVM partman should only add 
the minimal sizes of all "real" partitions together (256+12032).
Btw: It works if I specify minmal size 0 for the physical volume
