****** PLEASE UPDATE TO v9.12.28 (Stable) OR 10.12.28 (RC) *******
The unconfirming issue was caused by DS going too fast once and awhile and the view not being able to keep up with what inputs were spent. This caused double spends in about 2% of cases. To fix this I've introduced a limit where darksend will only denominate once a block.
If you have a long standing unconfirmed transaction, simply right click the transaction, copy the txid. Then execute the command "erasetransaction txid" in the console. After that reopen the client with the command -salvagewallet, and the money should be back.
It will still be possible to mix with clients that haven't updated, so avoid activating darksend for a day or so while the network updates. This update is backwards compatible, so masternodes need not update.

Fixed the reading/writing of the DisableDarksend option in the config and disabled darksend by default. If users want to enable it they can go into the configuration to turn it on.
