Relay operators see "Unexpected onionskin length after decryption: 58"
We've had one or two reports lately of people seeing
[warn] Unexpected onionskin length after decryption: 58in their logs.
It basically means that some client sent the relay a malformed (too short) create cell.
It's possible that this is a bug in our Tor client code, but I think it's more likely that somebody else is working on a Tor client, and has a bug in their code.
Since there isn't really much the relay operator can do about it, we should probably downgrade the warning to a protocol-warn.
