Weird data on multisig address in bitcoind. A bug?

[Sword Smith]

When I use the command "listsinceblock" in bitcoind I get some weird looking data for a multisig address. Can anybody explain this to me? Lookng at the txid, we can see that the two listed transactions represent the same transaction. Is this a bug in Bitcoin Core? The list for single signature addresses look correct.


The multisig address should only have one incoming transaction and no outgoing transactions as can be seen on blockchain.info:

Code:

please try to use it with proper parameters/arguments.

Code:

listsinceblock [blockhash] [target-confirmations] 

example: ./bitcoind -listsinceblock 0000000000000000365692b410bf843d6f7b7e0959c064f959776114e908fa8d

(this should list your tx as it s the previous block before your tx was made)


taken from the API list:

API description of "listsinceblock [blockhash] [target-confirmations]": Get all transactions in blocks since block [blockhash], or all transactions if omitted. [target-confirmations] intentionally does not affect the list of returned transactions, but only affects the returned "lastblock" value.

I don't use listsinceblock much, so perhaps I'm misunderstanding what I'm looking at.  It doesn't look like there's anything wrong to me.

As far as I can tell, you sent from the wallet back into the same wallet, and you are seeing both sides of that transaction, right?

Code:

{
            "account" : "",
            "address" : "34N5MSC3brnr183yRBBQYFRYNVmGf1ymhw",
            "category" : "send",
            "amount" : -0.00990000,
            "fee" : -0.00010000,
            "confirmations" : 13,
            "blockhash" : "0000000000000000064594fd44816f8ab656d2f2627848990c47f791e4276ad4",
            "blockindex" : 131,
            "blocktime" : 1405007016,
            "txid" : "7850528d3b57e3993d56b4f7cd90198fe3a329a4045bb240737758c6fb554b94",
            "walletconflicts" : [
            ],
            "time" : 1405006463,
            "timereceived" : 1405006463
 },

This appears to be an indication that a total of 0.0099 + (0.0001 fee) = 0.01 BTC was sent from the wallet to an address of 34N5MSC3brnr183yRBBQYFRYNVmGf1ymhw.  I assume that this is because you created a transaction spending the following 0.01 BTC output from this wallet and paying a 0.0001 BTC transaction fee:

Code:

"txid" : "e68f95873e41613d6610d43a2fd9919772fccce521fd7041ca14fd0da8627c09"
"vout" : "27"

Meanwhile . . .

Code:

{
            "account" : "",
            "address" : "34N5MSC3brnr183yRBBQYFRYNVmGf1ymhw",
            "category" : "receive",
            "amount" : 0.00990000,
            "confirmations" : 13,
            "blockhash" : "0000000000000000064594fd44816f8ab656d2f2627848990c47f791e4276ad4",
            "blockindex" : 131,
            "blocktime" : 1405007016,
            "txid" : "7850528d3b57e3993d56b4f7cd90198fe3a329a4045bb240737758c6fb554b94",
            "walletconflicts" : [
            ],
            "time" : 1405006463,
            "timereceived" : 1405006463
},

This appears to be an indication that a total of 0.0099 was received in the wallet at an address of 34N5MSC3brnr183yRBBQYFRYNVmGf1ymhw.
