Comment 12 for bug 445141

Proposing for Lucid:
- The change only affects new podcasts that are downloaded
- Test case:
1. Open Rhythmbox
2. Add http://deimos3.apple.com/WebObjects/Core.woa/Feed/cmu.edu.1335575211.01335575214 as a podcast (Ctrl+P)
3. Download 2 tracks in the podcast
4. Confirm the tracks are different (in the current version they will be the same)
