I think I'm on the list.

Crashes seem to be produced frequently with the following configuration:
Qsynth 2.5 or 3.1 with meters enabled
ALSA audio driver
synth.ladspa.active=no

The hardware supports 64-bit instructions, and is multi-core (Core 2 Duo). The
library and qsynth executable are 32-bit, according to the output of 'file':
/usr/local/bin/qsynth: ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped
/usr/local/lib/libfluidsynth.so.1.1.1: ELF 32-bit LSB shared object, Intel
80386, version 1 (SYSV), not stripped
