actually.. there's both favicon.ico and favicon.png... the effect of having these 2 favicons specified this way allows for the loggerhead turtle icon (favicon.ico) to be the favicon whilst browsing non-bzr branches. once you hit a bzr branch, it uses the stock bzr favicon (favicon.png) to signal that you're in a bzr branch.
make sense? try merging it on your own installation to see the effect.
