EXC_BAD_ACCESS crash

[MichaelWalsh]

Using TweetStation 1.5 (even though the app doesn't show a version) from the AppStore on my 3GS with OS 3.1.2.

1. Launch TweetStation
2. Settings
3. About
4. About and Credits
5. Tap Audio URL to Kevin MacLeod's twitter and let the view load
6. Tap <About] to get back and it crashed.

Have only been able to get this issue to repo once.
