I solved it by using
     import traceback, sys
     traceback.print_stack()
in the property

However, i'm not sure this is the best way.
I also tried to use the print_tb funtion from the traceback
function

traceback.print_tb(sys.last_traceback)

This produces an error
AttributeError: 'module' object has no attribute 'last_traceback'

So how can i pass a valid "traceback" object to the print_tb function 
and where do i find one?

Thanks,
