Hi there,
I'm new to sage, and made some sage scripts to improve my python scripts' performances. Then I load my script into a sage session, and run a test function.
When I get exception, it shows me the traceback with functions names only, without the instruction that triggered it. For example :
sage: f.runtest()
Generating keys ...

ZeroDivisionError: Inverse does not exist.
And I have no idea which line in KeyGen does trigger that ZeroDivisionError. Any idea ?
