Nautilus receives BadMatch X Window Error

["Shivram U" <shivaram upadhyayula wipro com>]

Hello everybody,
	This is regarding bug #78061:Nautilus fails to start on ffb 
type frame buffer when deflinear mode set to false
http://bugzilla.gnome.org/show_bug.cgi?id=78061

I could trace down the problem to nautilus-desktop-
window.c:set_gdk_window_background where we are trying to set the 
background of a window with of Pixmap of the RootWindow.

When we do this on solaris we get a BadMatch X Window Error. However it 
doesnt happen on linux.

The reason for this is on linux the visual classes are only available 
with the default depth, so all the windows are created with the same 
depth as the root window.
However on solaris (atleast on my machine) i am able to create windows 
with depth different to the depth of the root window.
In this case the default depth of the root window is 8 planes and the 
default visual class is PsuedoColor. And when the X Window Error 
occurs, the depth of the window on which we are setting the background 
pixmap is 24.

Shouldnt applications or gtk+ library take care of the depth the 
windows are created with, while dealing with pixmaps or windows at a 
different depth ?

Note: The BadMatch X Window error will also occur for the same reasons 
in gdkwindow-x11.c:gdk_window_set_back_pixmap.

Warm Regards,
Shivram U

P.S: Attached xpdyinfo output of my solaris machine.
