Cannot set values of a list of properties

Last autumn I wrote a short script to set up a database from scratch. It ran fine then, but not now.
The basic problem is that it will not set values for a list of properties:

tell application id "DNtp"
	set refLocation to create location "/Archief/" in database pnameDB
	set {comment, URL} of refLocation to {"archive_folder", "none"}
end tell
--> error "{«class DTco» of «class DTpr» id 46 of «class DTkb» id 4 of application \"DEVONthink Pro\", URL of «class DTpr» id 46 of «class DTkb» id 4 of application \"DEVONthink Pro\"} kan niet worden ingesteld op {\"archive_folder\", \"none\"}. Toegang niet toegestaan." number -10003 from {«class DTco» of «class DTpr» id 46 of «class DTkb» id 4, URL of «class DTpr» id 46 of «class DTkb» id 4}
```I can set properties one by one, but not as a list.
This worked initially (sep 2014). What changed?
I'm running DTP 2.7.6.

Version 2.7.6 was released in May 2014, therefore the only difference is probably an upgrade of the OS (Yosemite?). Anyway, this seems to work:


tell refLocation to set {comment, URL} to {"archive_folder", "none"}

Well, it’s not DTP, then. But I’m still on 10.6.8.
Anyways, rephrasing does work, thank you.
