In other words, a p2sh multi sig. Blockchain is bugged.
C# code with NBitcoin :
var tx = new BlockrTransactionRepository().Get(new uint256("5df1375ffe61ac35ca178ebb0cab9ea26dedbd0e96005dfcee7e379fa513232f"));
Console.WriteLine(tx.Inputs[1].ScriptSig);
var redeemScript = new PayToScriptHashTemplate()
{
VerifyRedeemScript = false
}.ExtractScriptSigParameters(tx.Inputs[1].ScriptSig).RedeemScript;
Console.WriteLine(redeemScript);
The funny thing is that the redeemScript is not correct. It is a 2 - 3 except that there is only one correctly formed public key. This make it non redeemable.
UPDATE : It was indeed spent. Investigating this miracle.
UPDATE 2 : My fault, there is 2 valid public key but one invalid one. Which means the spender stuffed data in the redeem.
