Broadcasting raw transaction fails

[checksum0]

On beta15 on windows, when I try to broadcast a raw TX using the cli interface I get this:

C:\Users\checksum0\AppData\Roaming\npm>lcoin-cli broadcast <TXHASH>
Error: Status code: 500
at HTTPClient._request (C:\Users\checksum0\AppData\Roaming\npm\node_modules\lcoin\lib\http\client.js:233:11)
at _request.next (<anonymous>)
at step (C:\Users\checksum0\AppData\Roaming\npm\node_modules\lcoin\lib\utils\co.js:33:22)
at succeed (C:\Users\checksum0\AppData\Roaming\npm\node_modules\lcoin\lib\utils\co.js:53:7)
at <anonymous>
at process._tickCallback (internal/process/next_tick.js:169:7)`

And the console shows:

[debug] (http) Request for method=POST path=/broadcast (127.0.0.1).
[error] (node) tx.hash is not a function
