yes, it is perfectly possible on a buggy platform called blockchain.info!
they actually used to show these kinds of stuff differently with a red warning on top of the page saying this address has done a double spend but i don't know why they removed it!
and this transaction is causing the bug in that block explorer: https://blockchain.info/tx/a35a5c0b334098c70bd2d955d0ecb23075eca72f42d3bf90b8a2f50fcddd07b9
and it is because the "balance" field is just a simple sum of (received - send) and since there is an additional "invalid" transaction which they don't drop for some weird reason the sum is negative.
To add to this for the people who has some difficulty understanding the difference between The Bitcoin Blockchain and https://blockchain.info < Believe me, there are loads of them >
https://blockchain.info is a site with software or tools like a Block explorer that is used to represent the Bitcoin Blockchain < It puts it into a nice GUI for everyone to read more easily >
So what Pooya87 is saying is that the tools or the software that https://blockchain.info is using is buggy and not the actual Bitcoin Blockchain. ^smile^
Use Blockexplorer.com as a alternative for https://blockchain.info
