I've been receiving "tx" messages across the wire with 0 inputs and 0 outputs. Literally the payload is 10 bytes { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 }. (Version = 1, 0 inputs, 0 outputs, LockTime = 0)

Any idea what those are all about? It's just occasionally. Do they have special purposes or are they just a misbehaving client?

Misbehaving client - I immediately ban nodes sending me a tx with no inputs, though still received 52 of such in the last 40 hours.
It's not a big problem for the network - much bigger problem are big txs with "correct horse battery staple" inputs, since these are technically valid (thus no reason to ban a peer), but they take so much more of our b/w (and CPU, if your node gets to verify them).
