gnome-shell (under gdb) output

Hi!

I've been testing gnome-shell from git (clutter, mutter etc. from git too).  I
initially got crashing as in https://bugs.freedesktop.org/show_bug.cgi?id=32918

I updated to latest xorg & mesa from ubuntu xorg-edgers PPA  (mesa
7.11.0-git20110119), this fixes the crashing but mouse events now mostly do not
work, and produce warnings like this:

(mutter:28983): Clutter-WARNING **: The required ID of 12107392 does not refer
to an existing actor; this usually implies that the pick() of an actor is not
correctly implemented or that there is an error in the glReadPixels()
implementation of the GL driver.

Clutter bug on this issue: https://bugs.freedesktop.org//show_bug.cgi?id=24408

What 3D driver are you using?  I would suggest trying the r300 gallium driver
if you are using the r300 classic driver.

I believe xorg-edgers is now shipping the Gallium driver:

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV370
