I just downloaded a clean copy of 2.0-alpha.9493 (running on MacOS X 10.8.5) and have a related problem. None of the base bundles were installed and the Bundles section of the Preferences window is not loading at all. I think there may be a deeper bug as the preference pane does not appear on the first 'CMD-,' but only on the second. The usual reseting and preference clearing have had no effect (not surprising at it is a clean install). Is this a known regression or is there something else I'm missing?
