I am not sure if this is a known bug, but I noticed that the wallet functionality of blockchain.info isn't dealing well with an orphaned block.  Here is my circumstance:

• I have an address in my wallet that I use to mine with p2pool
• When p2pool finds a block, my address receives some BTC via the generation transaction
• One of the p2pool blocks was orphaned
• The generation transaction for that orphaned block appears in my wallet transaction list and is marked as an unconfirmed transaction
• The BTC from that generation transaction appears in my balance even though it's not really available to me and never will be available to me

Everything seems ok except for the last point.  There appears to be no way for me to tell the wallet to only include confirmed transactions in the reported balance and so my balance is going to be "wrong" forever.

Is there a workaround for this?
