Comment 3 for bug 969569

The issue here is that there is no gtk3 implementation of Clearlooks. This is going to be a problem for pretty much everybody who has installed and enabled a custom gtk2 theme in Lucid and then upgrades to Precise.

I honestly believe that we shouldn't migrate the theme preferences from gconf to gsettings, and just accept that custom theme settings will reset to the defaults on Lucid -> Precise upgrades. I know we normally try to preserve user settings on upgrade, but this is still much better than leaving (possibly a significant minority of) upgraders with a broken theme.
