Steps to reproduce:

1. Create a 3D project
2. Add 3D Object -> Cube -
3. Window -> Search -> New Window
4. Verify that the "Search" window opens
5. Enter the search string "Cube"
6. Save search results to the "Project" list (diskette -> Save Project)
7. Leave the default name (it should be Cube) and click "Save"
8. Verify that the "Cube" query is selected in the "Project" list
9. Close the "Search" window
10. Go to "Project" -> "Assets" and find your saved query and select it
11. Verify, that query data becomes displayed in the "Inspector" tab
12. In the "Inspector" section find the "Project" tab and open it
13. Verify, that your saved query asset should be displayed
14. Double-click on it
15. Observe the "Console" window

Expected result: Selected item should be shown. No errors in the "Console" window.

Actual result: The selected item is shown but we get an error simultaneously in the "Console" window. Added screenshot in the "Attachments" section.
