Hmm.  Looks like the Debian binaries are stripped.  Drat!

Hard to tell without symbols, but this looks a bit like a problem I've
seen when running 2.6 without LD_ASSUME_KERNEL set.  Are you using
that environment variable?

If not, please try setting `export LD_ASSUME_KERNEL=2.4.19' in the
environment of jackd and all its clients.  (It may be easiest to just
set it once in your ~/.profile, then log in again.)  Let me know if
that eliminates your segfault.
