I suspect this is a bug in LADSPA SDK's sine.so plugin. At least some
versions of that plugin do a double-free upon exit. If you have a
recent version of glibc, it will detect this and emit a warning plus a
backtrace.

To verify this hypothesis, you can check whether you...
   - get the error with all setups containing LADSPA plugins
   - if you temporarily remove the sine plugin (/usr/lib/ladspa/sine.so
     or /usr/local/lib/ladspa/sine.so), the problem should disappear
