Re: Alignment trap - deprecation.pyo

ed,

Are you able to use the python interactive shell on your mini2440? I had 
a similar problem in that python would fail to even start (resulting in 
an alignment trap).

For me simply removing /usr/lib/python2.6/lib-dynload/readline.so kept 
python from dying on startup.
