This line points to a crash in following line [1], with maybe variable info or self being a NULL pointer:

   407                 if (g_strcmp0(info->active_port->name, self->earpiece_port) == 0) {

This upstream bug mentions the same source code line:

Adding a complete backtrace would probably be helpful.
This can usually be found in the journal after the
package systemd-coredump is installed, if possible.
