yo también estoy probando este componente y tengo el mismo problema, al<br>
presionar el boton de "Camera Depth" o "Images cnv" el proceso se cierra<br>
dando un error de violación de segmento (`core ' generado). Lo unico que he<br>
modificado del fichero de configuración del componente respecto al del<br>
repositorio es:<br>
