-----------------------
# Traceback (most recent call last):
# File "/opt/lib/python2.4/logging/__init__.py", line 740, in emit
# File "/opt/lib/python2.4/logging/__init__.py", line 718, in flush
# AttributeError: 'maya.Output' object has no attribute 'flush'
# Warning: The callback " has already been added. #
// Warning: The callback " has already been added. //
----------------------------------
Don't know how to trace this. Any idea?
