Something odd going on here...

how is it on testnet that after about 10 minutes I end up with two addresses for the account 0 ?

these are the steps i am seeing to reproduce..

1, start darkcoind
2, tail -f .darkcoind/testnet3/debug.log
3, wait till synced up.
4, find local wallet.
5, ./darkcoind getaccountaddress 0
mmbRNmQvzbhu5N7eUrznovgBtyWVeLzGQk

6, send 1000 to kzGQk address
7, wait for 1000 to show up.
8, then when i ask what the 0 address is i get a whole new address??  WTF ??
9, ./darkcoind getaccountaddress 0
mvjjeg9gcukVEVbanKLemKRk3ZqAX22Yyu

you can see now that there are two addresses for account 0

./darkcoind getaddressesbyaccount 0
[
    "mvjjeg9gcukVEVbanKLemKRk3ZqAX22Yyu",
    "mmbRNmQvzbhu5N7eUrznovgBtyWVeLzGQk"
]

I have tried removing the testnet3 folder, stoping and starting darkcoind again, removing the entire folder...

    "version" : 100701,
    "protocolversion" : 70014,

}


Anyone have any thoughts??
