Hello everyone!

Since I am still locked at the newbies section, that's where I post this (suspected) bug.
I have been trying the multisig BIP 16 using the latest 0.6.3 client on Ubuntu 64 bit.
I was trying to create 2 from 3 sig address, but it behaves like 3 out of 3 sig address.

$ bitcoind addmultisigaddress 2 '["04d4f81d9c28413d3019a202e63a828c884dcaffa094a9e66fb8dec623a1445d3fe099ca7c3087c 13ac6b62ad7f547eff25df552e94e12f6fbfc4535c1c2b4b78a","0420c41cb722082943e7da602557b2e28a84ebad90bdfbae8499d9ae77a3752570d711649b2e54f 87b9064b7dc72f5f96203a782e82cfc08a5ac576d933ca92de1","04eb3fbbd85992aeb3ef8d752f733661349fcbfce2683200b90009c8b4e713ffd93da9fc7f840e2 2cca18ed6d66ed51cdca729586f0c5b17f9f4f3c493ba7cdab7"]'
3G2v3VJZ46fjgLMqEF3CzLq3k9FPMgauh4
$
$ bitcoind validateaddress 3G2v3VJZ46fjgLMqEF3CzLq3k9FPMgauh4
{
"isvalid" : true,
"address" : "3G2v3VJZ46fjgLMqEF3CzLq3k9FPMgauh4",
"isscript" : true,
"ismine" : false,
"script" : "multisig",
"addresses" : [
"12tbLXQkERTB6Sq99EHptWuWJJgXqkZb4z",
"18pu5kF3kf9N8Ft5xuTGD2v3EdB9Hahwgh",
"19ARwmH1H1QMFSjmB14fyA4QrZigiM8sNV"
],
"sigsrequired" : 2,
"account" : ""
}

I have sent 0.1 BTC to the 3G... address directly from instawallet: 3dd40692d5594ee1302c3a6fce4c9086af3324dfadabf97150c8c5ea7ff78f1a
as well as the following:
$ bitcoind sendtoaddress 3G2v3VJZ46fjgLMqEF3CzLq3k9FPMgauh4 0.05
6c2f5a608fb3ef3e64e728ad430f60bbd6857de662b152dc2ef55eb25fdf2e93

I have made a backup of wallet.dat before importing.
Then I imported the keys #1, #2, #3
$ bitcoind getbalance
0.21700000
$ bitcoind importprivkey 5Jm...
$ bitcoind getbalance
0.21700000
$ bitcoind importprivkey 5KQ...
$ bitcoind getbalance
0.21700000
$ bitcoind importprivkey 5Ji...
$ bitcoind getbalance
0.36700000
Also in a different order (#3, #2, #1) the result is the same:
$ bitcoind getbalance
0.21700000
$ bitcoind importprivkey 5Ji...
$ bitcoind importprivkey 5KQ...
$ bitcoind getbalance
0.21700000
$ bitcoind importprivkey 5Jm...
$ bitcoind getbalance
0.36700000

And also when I try to import #1, #3, #2  – same.

Did I miss something?
If there is a need, I could give the private keys (well, at least 2 of them, and to someone I trust ;-))

Bugs should be reported on GitHub, but I don't think this is a bug. Bitcoin-Qt and bitcoind don't support N-of-M multisig transactions yet except for the one case where 1) it has all the keys; 2) it is explicitly told about the multisig address before the coins are sent (-rescan probably works too).
