Ok ... this is odd.
I tried gregory's suggestion of redirecting the stdout stderr to a
text file. This worked. I could see all the logging information.
However, there was no error to see this time ... the application
worked completely without any problems.
I also then tried Jon's suggestion of

Cron normally sends you mail if a cron task generated any output (this
should include error messages).

I've included a switch to include or exclude the logging to console.
When logging only to file, the script runs fine.
Of course, I still don't understand why dual logging, and specifically
to the console, causes a problem and if anyone has any comments about
the dual output logging code above

Which is true, but again, cron should report the environment in the mail
message. For example, here are

Put your main function in a big
try, except. Catch any and all
errors and log them. Example:
def main():
try:
do_something()
except Exception, error:
log(ERROR: %s % error)
log(format_exc())
Hope this helps.
cheers

James ... thanks for the suggestion. I have done this and the error
logging usually catches all my errors and logs them. I wondered if
logging itself was failing!
Philip ... thanks also. I did wonder about making the everything
explicit. I've seen that mentioned elsewhere. Writing out the stdout
use UNIX mail command: crontab will send letters to you and you can
look at traceback there.

Try using the following at the begining of your Python program:
import sys
sys.stdout = open(out.txt,w)
sys.stderr = open(err.txt,w)
Then whatever would normally go to stdout or stderr goes to text files
instead. You will see everything that happened.
