Comment 11 for bug 1010487

OK, some new light on this: first off, applying the main changes from this branch fixes the colors: http://bazaar.launchpad.net/~xnox/ubiquity/quantal-proposed

Then, the widgets still don't look like they're rendered by Gtk3 (see attached screenshot). However – and this may sound a bit absurd – after installing the light-themes package Greybird is correctly rendered in Ubiquity.

I'm not talking about installing the light-themes package and setting Ambiance or Radiance, just plain "sudo apt-get install light-themes". After purging the light-themes package, we're back at what you can see in the screenshot. I hope someone can explain this to me...

The only thing I can think of now is that xfsettingsd somehow doesn't set the Gtk-theme correctly, as Gtk2 is also broken there (right-click the window-border to test Gtk2) and installing light-themes triggers some gconf switches...
