Quitting on Mac sometimes leads to a "Wirk Quit Unexpectedly" dialog

[designatednerd]

This is intermittent, but I've seen it more than once, usually after Wirk has been running for a while. Usually quitting by clicking on the icon in the dock and selecting Quit rather than command-Q, not sure if that makes a difference. OS X 10.8.3.
