[Zope] Error messages from external methods

[Cliff Ford]

I forget when this change occurred (2.5?), but you should be able to 
find the traceback (with line numbers) in your Site Error Log. I think 
you might be able to put the traceback back into the error message by 
outputting error_tb in your standard_error_message. Don't know if this 
is a good idea!
