Emil,
Actually it is probably something else. I had a user with YellowDog
Linux 2.3 try sparky against python 2.1.1 and tcl 8.3.3 and he segfaults
as well. Are you on i386 or ppc debian? If i386, I would be very interested
if sparky segfaults on that arch as well. It has been built on redhat
linux for i386 by the author so it shouldn't segfault on that arch.
