Gtk theme error -- Theme parsing error: gtk.css:6:58: Failed to import: The resource at '/org/gnome/adwaita/gtk-main.css' does not exist

I am using CLDX right now, when I open some gtk software, the following messages always come up.

I guess the reason is that /org/gnome/… does not exist.

Gtk-WARNING ****: Theme parsing error: gtk.css:6:58: Failed to import: The resource at ‘/org/gnome/adwaita/gtk-main.css’ does not exist

Just want to know how to fix this problem, even if it does not affect anything.

This problem has popped up in Red Hat and Debian in the past… take a look

Thanks for your reply. According to the links you gave above,

Just (re)install gnome-themes gnome-themes-standard gnome-themes-extra,

but nothing changes.

Seems package location and refrences not up to date.
I will occassionaly find common items not working as in your case.
Sometimes my personal keyboard shortcuts will fail to work while the meta references in the config continue to be in order.
In these cases an update will usually reveal the problem or a dependency and thereby a cure.
Try, as root user of course. Many times will do the trick.

Thanks for your reply.

One interesting thing is that the mistake does NOT show up if I run it under root.
