Any chance of a stack showing what we're doing?

When I tried this I got a SIGSEGV in nsWidget::DispatchEvent
(nsWidget.cpp:1463) NS_ADDREF(aEvent->widget);
Naturally widget was null at this point :-(

Neil: That crasher should be fixed (bug 230738).

Attachment: fix

Oops, sorry, this is a different problem.  Dispatching the event clears the
widget, so we need to set it again (as the code was doing before).
