--- Comment #6 from Richard Freeman <rich0 at gentoo.org> ---
I've got some more data points here.  While the segfault occurs client-side, it
appears to be triggered by a change server-side.

I can reproduce the problem if the X11 server is xorg-server 1.13.0-r1 (Gentoo
version number).  The problem does not occur if the X11 server is 1.12.4.  The
behavior is the same if either mesa 8.0.4-r1 or mesa 9.0 is installed on either
the server or the client side.  The behavior is reproducible if the client is
running on a separate host from the X11 server, if the X11 server is running
1.13.0.

Note also that the problem does not occur with xorg-server 1.12.4 even with the
same versions of xf86-input-evdev/keyboard/mouse and xf86-video-ati as were
running in 1.13 (though they do need to be recompiled against whatever server
version is in use).  So, I can make the problem appear or go away by only
changing the version of xorg-server, even when using the older server with the
newer drivers.  

I'm tempted to break out the commit log and start bifurcating it next, but if
anybody has any pointers I'm all ears...
