GTK3: can't load Adwaita stylesheet

[Fabrice DELENTE <fdelente mail cpod fr>]

Hello.

I'm not using gnome, but I installed GTK3.

I have compiled Evince 3.1.90, which uses GTK3, and installed the
Adwaita theme.

When I start Evince, I get

(lt-evince:7563): Gtk-WARNING **: Could not load named theme "Adwaita": Error parsing stylesheet

even though I have, in ~/.config/gtk-3.0/settings.ini

[Settings]
gtk-theme-name = Adwaita
gtk-fallback-icon-theme = gnome
gtk-toolbar-style=GTK_TOOLBAR_ICONS

and I have Adwaita in /usr/share/themes/Adwaita/gtk-3.0:

$ ll
total 45
drwxr-xr-x 2 root root   480 2011-03-29 18:50 assets/
-rw-r--r-- 1 root root  3525 2011-08-16 17:30 gtk.css
-rw-r--r-- 1 root root 32240 2011-03-29 18:49 gtk-widgets.css
-rw-r--r-- 1 root root   237 2011-03-29 18:49 settings.ini

All the files in this location are readable by everybody.

What more must I do?

Thanks!
