Bug#516347: debian-installer: guided-with-lvm no longer allows ? primary partition.
Similar behavior observed with recipes defining only one primary partition (/boot).
The effect of the bug was dependent on the size of that partition.
If changing the partition size (try 200 200 200) allows partitioning, then we're talking the same bug.
Try a few more sizes as I suspect it also depends on the drive parameters (e.g. size and CHS).

90 and 94 don't work, the others work o.k.
