I'm trying to debug this extremely weird crash that we keep having which is being caused by URLLoader. For some reason it will spit out an error message "Error #2044: Unhandled ioError:. text=Error #2032: Stream Error..." but when I add an IOErrorEvent.IO_ERROR it goes away and the event handler never gets called. Any idea what the hell is going on? Because this is really damn weird and confusing as hell. Is this event handler required or something? Because that's what it seems like.
