After getting Allan's permission on #webkit, I used webkit-patch land-attachment to green things up without waiting for the cq.

I am seeing the same ASSERT triggering in webaudio. There seem to be another instance of ActiveDOMObject there too. Is it possible that we are missing the same fix there?

It is possible. I have checked all classes directly derived from ActiveDOMObject, and all classes indirectly derived from ActiveDOMObject used by Qt. But I might have missed a classes indirectly inheriting from ActiveDOMObject in modules not used by Qt.

If this is the case, it can be fixed by calling suspendIfNeeded() in the create class.
