Did you think to test your code before posting it?

sys.exc_type is deprecated (you should use sys.exc_info() instead), but 
neither will tell you whether the program is exiting as a result of an 
exception when called from an atexit function, by the time the atexit 
function is called the exception is no longer accessible.

As Larry Bates suggested, the OP needs to use a sys.excepthook. 
Unfortunately he doesn't test his code either (the parameter 'traceback' 
conflicts with the module 'traceback'), but at least the principle is 
correct.
