(pulseaudio:12561): GStreamer-WARNING **: 14:24:23.128: External plugin loader
failed. This most likely means that the plugin loader helper binary was not
found or could not be run. You might need to set the GST_PLUGIN_SCANNER
environment variable if your setup is unusual. This should normally not be
required though.

(pulseaudio:12561): GLib-GObject-CRITICAL **: 14:24:23.146:
g_param_spec_internal: assertion 'g_param_spec_is_valid_name (name)' failed

ERROR: Caught a segmentation fault while loading plugin file:
/lib64/gstreamer-1.0/libgstfluidsynth.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap --gst-disable-registry-fork and debug.
