A question here is whether you want a DBusError to explain _why_ the 
validation failed, e.g. if you're implementing dbus-send you'd want to 
say "path does not start with slash" rather than "invalid path"

I would say yes; if people don't care about the why they can pass NULL 
for the DBusError, but for validation I'd think you often want the 
error, since it's likely to be a case where the user was specifically 
supposed to provide a valid dbus path or name.
