I would recomend you to be rather quiet. of course you don't need to wait for any block the transaction appears by it self and will be writen maybe on the paper lol   It is zerocoin mint over the mint. you wait "strFailReason = _("there needs to be at least 2 mint coins in the accumulator with 6+ confirmations");"

6 confirmation in blockchain for 1st mint zerocoin + 6 confirmations 2nd mint of minted you know better call it 2 way ghost or what ever it is still zerocoin procedure made by Reuben Yap and Zcoin team
