When JSEventListener::handleEvent() grabs the window's ExecState, the ExecState already has an exception set. I'll get to the bottom of this.
Created attachment 21962 [details] ExecState::setException() backtrace Here's the backtrace for the call to ExecState::setException() that sets the offending exception.
There is nothing done to propagate exceptions in the Netscape plugin API, so they stay set on the window object until the next time the window object is used. I am not exactly sure what should be done, especially in this case, where the call is ultimately from JS code. Perhaps someone with more Netscape plugin knowledge can fix this or let me know how it should be fixed.
