My suspicion lies in python's pipe code, possibly in conjunction with
GCL readline.  Can a segault be reproduced with axiom intel
standalone?  Alternatively, can someone please try to reproduce
setting the TERM environment variable to "dumb"?  Might need to check
strace -f on the process to make sure Python does not setup the pipe
environment as a readline capable terminal (e.g. vt100).  If one can
get to axiom at all over the pipe, try doing )lisp (si::readline-off)
at the beginning, or putting this into some axiom rc startup file or
something. 

Please feel free to report all Debian binary bugs to the Debian BTS
via 'reportbug'.

Great!  Please keep me posted.
