I think I've nailed it. It seems that doing one of these two keeps it
from crashing:
echo 0 > /proc/sys/kernel/exec-shield
or
echo 1 > /proc/sys/vm/legacy_va_layout

I realized that after booting the computer, I was able to start the
framework on Qemu once, but on subsequent attempts it crashed -- even
though I did the killall, restarted Scratchbox and scanned through all
the processes to make sure nothing remained. So I looked into the memory
protection settings of my kernel such as exec-shield, and it seems
enabling the legacy virtual address layout does the trick. My impression
is that this a Red Hat/Fedora specific problem.
