Cool. From looking at the backtrace a quick fix would probably be to
disable LADSPA support in FluidSynth (you probably aren't using it
anyways?) Just don't explicitly enable it during configure time and it
should not be compiled. There may be something more sinister going on
here though, since I really don't see how its getting to
delete_fluid_settings() from fluid_settings_getint(). Something might be
broken with the LADSPA code. I may have to get ~FluidSynth installed to
figure this out. Any quick pointers to getting things setup? Cheers.
