Thanks Gabriel, Indeed, there is corrupted copy_reg.py file residing in my $PYTHONPATH folder, as opposed to the standard one from the installed package. Thanks a lot for your helps!

Maybe your copy_reg.py is broken, or you have another copy_reg.py hiding the standard one. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
