WidgetPreview : error 500 - NoClassDefFound

Hi people,

I've been trying to test a widget of my creation on http://dev.bubbletop.com/widgetpreview but I always get a 500 error, even with the HelloWorld widget from the site (I simply copy it to the "Edit" tab, then switch to the "Preview" tab.
It's a bit annoying as I can't test my widget in this case :(
