how to debug when "Segmentation fault"

[Maksim Kasimov]

looks sad :(

ok, until the decision not found, i've run my script (if someone have the same problem) using sh-script like this:

#!/bin/sh
while true
do
myscript.py
echo "scrip was fault" | mail -s "run.sh" maksim.kasimov at gmail.com
done



... still works ;)
