Description of problem:
Got segfault from mutter:

I am manually pasting in the abrt log, as it failed to connect to Bugzilla.

I have the corefile, so let me know if there is additional info needed.

I booted up/logged in with gnome-shell set as my "default".

I created some windows (gnome-terminal, pidgin), then created 2 additional workspaces, Then created some more windows in the first 2 workspaces (firefox, qemu-kvm).

Finally, in the third workspace, I created a gnome-terminal window, and I was attempting to move it to the upper left corner of the display when I got this crash.....

Window and compositing manager based on Clutter

Mutter is a window and compositing manager that displays and manages
your desktop via OpenGL. Mutter combines a sophisticated display engine
using the Clutter toolkit with solid window-management logic inherited
from the Metacity window manager.

While Mutter can be used stand-alone, it is primarily intended to be
used as the display core of a larger system such as gnome-shell or
Moblin. For this reason, Mutter is very extensible via plugins, which
are used both to add fancy visual effects and to rework the window
management behaviors to meet the needs of the environment.
