OK, sounds like something's wrong with NPTL on a 586... could you test
further? What I'd really like would be a core dump; unless core dumps
are disabled (ulimit -c) you ought to have gotten one when aptitude
crashed.
FYI, with the new libc6 installed and 2.6.0-test8 you should be able to
say "LD_ASSUME_KERNEL=2.4.22 aptitude" and that should work (disabling
NPTL).
So if you can get up a core file, load it up using
LD_ASSUME_KERNEL=2.4.22 gdb aptitude core
and give us the output of
info registers
disassemble
