Instances won't render – 'NO_GUID' – (Harpwood Trail)

It's not specifically related to the 'Harpwood Trail' scene – I get the error in other scenes as well – but it seems that Reality has a problem with rendering instances.
In the LuxRender GUI I get notified about a lot of errors in the log file.
The Log tab then shows me a tremendous amount of errors " Error: 41] Unable to find instance named 'NO_GUID'"
As said, this happens in other pre-made scenes as well.

The only way around is to delete all the instances and recreate them all, placing them all as desired and then it works.
This, however, costs hours of work with prefab scenes like Harpwood Trail.

I checked and with Luxus it works; the prefab scene renders fine.
So, it is not a limitation of LuxRender, but definitely coming from the Reality plugin.

What should I do to overcome this?
