I just upgraded my ThinkPad T60 from CentOS 6 to Fedora 19 and
whenever I connect it to the dock with a second VGA monitor connected
to the dock, gnome_shell crashes. This worked fine under CentOS 6 and
the keyboard and mouse continue to work, but I can't do anything with
the shell.

The problem is  that you are over the texture size limit of your GPU:

glxinfo -l | grep GL_MAX_TEXTURE_SIZE

(should be 2048 in your case). So your combined res cannot be wider
then 2048 in either direction).

Adding the second monitor exceeds the limit.

The problem is also that we're setting a root window property containing
that limit, and simply not looking at its value.

ergine:~/git/gnome-settings-daemon% xprop -root | grep _GNOME_MAX_SCREEN_SIZE
ergine:~/git/gnome-settings-daemon% git grep -c _GNOME_MAX_SCREEN_SIZE
