I just built GIT HEAD (328b26) and was playing about with 'getblock' and 'getmining info' when a new block was generated. This was the newest block initially:

$ bitcoind getblock 2ef0d1af72aac8cb39fdf061fcbcf3aa5c26f04150f9aaef4ed
{
    "hash" : "00000000000002ef0d1af72aac8cb39fdf061fcbcf3aa5c26f04150f9aaef4ed",
    "blockcount" : 166022,
    "version" : 1,
    "merkleroot" : "1d4723fd632af0dd2b3a6bd3559fab3dc401732100a6bda1c29fd27cfca0d1b3",
    "time" : 1328784001,
    "nonce" : 2228820364,
    "difficulty" : 1379647.43921429,
    "tx" : [
        "2459f016f5733e819a3251ec31a1ebca5be4d33c74cc52c29d424f2665a9ec8d",
        "aefcccaf2e6e478d0654737b69a5ac0b3f3bd330869323352b630abeefe35706",
        "f5ba47853adfeb63b86d112e59614ac5ce03bea5f7c7d89efcb0ba069879fc08",
        "e4e4f056c27893ea56f8825fd3b770c35ac7e9ba313474742b5bc9d5c49432e4",

        "f7f539536d10c96cf64e62e130c3f155b324e8ded7357a220bfacc124bd40a9b"
    ],
    "hashprevious" : "00000000000009ce9f73ebcfb0180d4ae30fc508897cbff7ccda7e2bc9adf7f8"
}

Then I looked at the previous block:

$ bitcoind getblock 9ce9f73ebcfb0180d4ae30fc508897cbff7ccda7e2bc9adf7f8
{
    "hash" : "00000000000009ce9f73ebcfb0180d4ae30fc508897cbff7ccda7e2bc9adf7f8",

}

And back to the newest block:

$ bitcoind getblock 2ef0d1af72aac8cb39fdf061fcbcf3aa5c26f04150f9aaef4ed
{
    "hash" : "00000000000002ef0d1af72aac8cb39fdf061fcbcf3aa5c26f04150f9aaef4ed",
    "blockcount" : 166022,
    "version" : 1,
    "merkleroot" : "1d4723fd632af0dd2b3a6bd3559fab3dc401732100a6bda1c29fd27cfca0d1b3",
    "time" : 1328784001,
    "nonce" : 2228820364,
    "difficulty" : 1379647.43921429,
    "tx" : [
        "2459f016f5733e819a3251ec31a1ebca5be4d33c74cc52c29d424f2665a9ec8d",
        "aefcccaf2e6e478d0654737b69a5ac0b3f3bd330869323352b630abeefe35706",
        "f5ba47853adfeb63b86d112e59614ac5ce03bea5f7c7d89efcb0ba069879fc08",
        "e4e4f056c27893ea56f8825fd3b770c35ac7e9ba313474742b5bc9d5c49432e4",
        "473e032356c42af5ac8fd85716128e6d776330fb58835bcf72b913b1daf4b2a5",
        "f7f539536d10c96cf64e62e130c3f155b324e8ded7357a220bfacc124bd40a9b"
    ],
    "hashprevious" : "00000000000009ce9f73ebcfb0180d4ae30fc508897cbff7ccda7e2bc9adf7f8"
}

Then I checked the mininginfo for the first time:

$ bitcoind getmininginfo
{
    "blocks" : 166022,
    "currentblocksize" : 0,
    "currentblocktx" : 0,
    "difficulty" : 1379647.43921429,
    "errors" : "",
    "generate" : false,
    "genproclimit" : -1,
    "hashespersec" : 0,
    "pooledtx" : 9,
    "testnet" : false
}

Then again, almost immediately, and noticed the block count had gone up by one, and that the 'pooledtx' count had gone crazy:

$ bitcoind getmininginfo
{
    "blocks" : 166023,
    "currentblocksize" : 0,
    "currentblocktx" : 0,
    "difficulty" : 1379647.43921429,
    "errors" : "",
    "generate" : false,
    "genproclimit" : -1,
    "hashespersec" : 0,
    "pooledtx" : 18446744073709551608,
    "testnet" : false
}

I see nothing obvious in the code that would cause the pooledtx count to be such a massive number. This must be a bug.
