In case any one else is wondering, the vca_app is the Voice Command Audio application. It builds voice commands from the audio devices you have connected to the system (so you can say "Play Elvis Presley" and it knows what to do.) If any of your audio tracks contain certain characters which the VCA_App can't handle, it fails with this serious error. Unfortunately, the only solution I've found is to remove the tracks from your device or rename them on your computer.
