This will apparently be fixed when wingpanel next rebuilds on launchpad. There's been an api change in gala.

[davidmhewitt]

This has not been resolved by a rebuild of wingpanel, the backtrace remains the same.

I think #279 and #280 have a good chance of resolving this.

[davidmhewitt]

Resolved in latest build.
