As was disclosed today, several wallets have been found not to handle well
the scenario of reverted transactions at zero confirmations. This includes
showing an increased balance to the user without decreasing it when a
transaction is replaced and also preventing the user from being able to
spend other valid coins.

You can test the behavior of your own wallet (either that you use or
develop) and read more about it in this new tool:
