In this particular case, the error is caused by an external program, so
printing a Python backtrace only serves to confuse the user.
While there might be a few bugs still hidden in sugar-emulator (you
recently fixed one, thanks!), in the majority of cases it's a problem on
the users system - e.g. the infamous Ubuntu Xephyr D-Bus policy issue.
So I'd rather have a developer grep the source (if (s)he really doesn't
already expect it to live in sugar-emulator) than lots of users getting
confused about the traceback (remember that this was the reason I filed
the ticket in the first place).
