On my system, running the simple smtplib Example
from the Documentation results in a segmentation fault.
Execution stops and no mail is submitted.

I debugged into the Python source code, but my
understanding of the inner mechanisms doesn't
suffice to fix the problem.

I update my system periodically using "apt-get update ;
apt-get upgrade". I don't remember, when it was the last
time Python was upgraded.

I made the files availabe:
