Because they aren't dbus errors. If your handler has some stupid code
like `(car 42)', the resulting lisp error `(wrong-type-argument listp 42)'
shouldn't be shown as *dbus* error.
You're free to write a handler which returns any error as dbus error, if
your program logic requires this.
Best regards, Michael.
