Cool. Although you can probably remove this:
    "desktop-file-name-prefix": "(Nightly) ",

Unless you're using this to create nightly builds.

Yeah, this is failing to register the dbus name
"org.prefixsuffix.application", because the sandboxed app is only
allowed to own names of the form "org.gnome.PrefixSuffix" and
"org.gnome.PrefixSuffix.*". This is to avoid conflicts with other apps
and with host services. You need to rename the app (or change the code
to use the new dbus name).
