Does this indicate a double-spend attack then?

No, it is not technically a double-spend, but it might indicate some malicious behaviour.

Can also happen when you bump a fee in a tx. See my answer for more info.

<p>If you have two or more transactions in your wallet that spend the same output, that field will list the other ones.  That should normally never happen, because bitcoin-qt will refuse to create a transaction that spends an already-spent output.  But if your wallet is corrupt or there's some other problem, it might happen.</p>

<p>It looks like this happens if you bump a fee with some wallets. The old tx will report <code>&quot;trusted&quot;: false</code>, and both the old and new tx will list the wallet conflicts. The property <code>walletconflicts</code> will contain the tx ids of all conflicting transactions (so in a case of one replacement, both the first and the next tx will report the other tx respectively).</p>

This is new. It is a field, which contains txids which hold the same data as the original transaction (but has different txids).

See [ID-malleation bug](http://www.cryptocoinsnews.com/news/bitcoin-transaction-malleability/2014/02/16)

It looks like this happens if you bump a fee with some wallets. The old tx will report `"trusted": false`, and both the old and new tx will list the wallet conflicts. The property `walletconflicts` will contain the tx ids of all conflicting transactions (so in a case of one replacement, both the first and the next tx will report the other tx respectively).
