Comment 4 for bug 188415

It's working quite nicely at the moment - all the important widgets get themed properly.
There are still a couple of crashes and bits of odd behaviour when you use it within Gnome, which I think will need to be fixed before we can include it in Hardy.
I'll continue working on it and keep you posted.

I've spoken with the author of GTK-KDE4. It's a script that grabs snapshots of Qt widgets and saves them to make a GTK pixmap theme. Since it doesn't actually use its own theme engine I don't think it will ever be able to be totally accurate, but what I've seen of it does look quite good.
We decided that since we're taking two completely different approaches there wasn't much point merging projects.
