I tried the following things:
- Ran check and repair - a few minor issues, but nothing major.
- I don’t have the privacy filter on.
- I upgraded to the latest Gramps and tried again, but unfortunately the error persists.
The other frustrating part is that it seems to be impossible to full out a bug report because it’s not possible to select the Gramps project on the bug reporting page: Select Project - Gramps - Bugtracker – Free Genealogy Software
I even tried in other browsers and with another user - but no luck.
