I transferred bitcoin from Coinbase to my QT bitcoin wallet 5/13. Coinbase shows transfer confirmed, blockchain.info shows 1600+ confirmations. QT wallet shows the same receiving address where Coinbase sent the correct amount of btc. My QT wallet shows the btc received, but indicates it's unconfirmed. I let Coinbase figure the fee for the transfer and didn't change it before sending the bitcoin since the fee didn't seem out-of-line.
Any other option available to me other than to uninstall then reinstall the wallet, then wait 4-5 days for it to resync to see if that helps? There are a bunch of command-line options in this wallet's options but I'm a newb and have no idea what any of these options do or how to input any of them even if I thought any of these commands would help!
Are you sure your wallet is completely synced?
If it it, you could try to rescan your wallet by starting it with the correct parameter (./bitcoin-qt -rescan)
