Accidentally created new addresses - how to delete?

[fabianhjr]

I had been trying to delete an address(No transactions whatsoever) that I created accidentally. The stock client doesn't seem to allow me and the info appears to be in wallet.dat(Which, I don't want to tamper with because I have my real wallet there and fear to lose it)

Does anyone know what to do?

Unless you accidentally created thousands of addresses, thereby bloating your wallet.dat, don't worry about it.

Addresses don't touch the network, and shouldn't slow down your client.  Just ignore them.

You'll soon be creating an address per transaction (recommended), so you'll wind up with a bunch over time.
