I've since duplicated it building a different GWT project, so I'll report the bug against GWT.

I also see a similar crash in Eclipse if Eclipse is using webkit (the default) AND Google Talk is installed. Either uninstalling GTalk or using -Dorg.eclipse.swt.browser.DefaultType=mozilla
works around that. So the GWT bug might be a JDK bug. Thoughts?
