Rotated blocks displaying "error" texture in held and head slots

When using /replaceitem or trying to directly summon a mob with equipment in the head slot, all "rotated" blocks show the "error" texture.

Command to recreate issue:

/entitydata @e[type=ArmorStand] {Equipment:[{id:log,Damage:4},{},{},{},{id:stone_stairs,Damage:1}]}

This affects all blocks that have damage values that are a rotation of another damage value, including, but not limited to:
log (damage value 4+)
log2 (damage value 2+)
stairs (damage value 1+)
quartz_block (damage values 3+)
rail variants (damage 1+)
piston variants (damage 1+)
wooden_slab (damage 6+)
stone_slab (damage 8+)
