I'm not sure this is a valid bug. Yes three tracebacks look more intimidating, but if we show that any unfamiliar will be intimidated no matter if only the last or all three are shown.
If it's changed it shouldn't be Python 3 specific but work on both versions and then something like that it only prints the error message to the console and the traceback to a log. Problem with that solution however is when the log wasn't activated because than the traceback is lost.
