Oh, I don't know exactly. It's just what I thought of when you said  
that the problem occurs when logging to the console but not to files.  
I don't have a deep Unix background so I can't give you the details on  
what "the console" means to a cron job.

In my experience, the environment in which a cron job runs is  
different from the environment in which some command line scripts run  
(remember my earlier suggestion about needing to explicitly set the  
PATH?) and so if the console for a cron job differed from the console  
that a Python program sees when run in a terminal, that would not  
surprise me.

Hope it's a useful suggestion
