I don't think it has to do with a particular email....

The random.py module, a standard part of the Python installation, is
trying to verify that your numeric co-processor works reasonably
well.  It multiplies 2.0 * pi (3.14159265359 on my system).  Then it
compares that result with 6.28318530718, as given above.  If the
computed value and the hard-coded value are too far apart, it throws
this exception.

My guess is that you have either a flaky co-processor or memory
problems, such that, at times, this comparison fails.
