gnome_shell crash when connecting a second monitor on a ThinkPad T60

[Dave Johansen <davejohansen gmail com>]

Please let me know if there's a more appropriate list to post this on,
but from examining the list of options this seemed like the most
appropriate one.

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.

Here's the output from /var/log/messages:

I've posted on the Fedora users mailing list, but no luck so far:

Any advice on things I can do to help diagnose/fix this problem?

Thanks,
Dave
