- Patch 13738 by TDobes: there was a major theming issue I missed in my bug-testing after the multi-site patch landed.  Styles now seem to have their description field filled with the filename of their parent theme/template rather than the theme_key of the parent. This is a problem because init_theme still expected to see the theme_key and therefore dropped back to the base theme (no theme at all).
