GTK bug

["fetrin" <fetrin uol com br>]

Hello.

I have a problem with my gtk
I installed Debian System, but I updated the gtk.
If I start the gimp aplication, the menus are background black.
In console, I have a message

Gdk-WARNING **: gdk_window_set_back_pixmap(): pixmap must have a colormap

What´s the problem?
Can you help me?

thanks

Fernando
