Error using "Relationship path between <persons>"

[csam]

Gramps 6.0.3 on MacOS

I’m trying to use the built-in filter “Relationship path between ”.
In the filter editor I add the “Relationship path between ” and add two person ids using the [Select] bottons.
When I test the filter, I get the following error:

129366391: ERROR: grampsapp.py: line 188: Unhandled exception

Wonder what I’m doing wrong?
Running simple filters like “People without a known birth date” works fine.

Looks like this broke recently as it worked on 5.1.6 . I can file a bug if you dont want to. To fix, edit:

/Applications/Gramps.app/Contents/Resources/lib/python3.13/site-packages/gramps/gen/filters/rules/person/_relationshippathbetween.py

change line 129 (and –> &) from

for person_handle in firstList and secondList:

to

for person_handle in firstList & secondList:

ADDED: bug filed: https://gramps-project.org/bugs/view.php?id=13949

This was fixed in v6.0.4. See PR #2085 “Fix regression in relationship path between people filter”.

Installed version 6.0.4 and can confirm, that Relationship Path Between works fine.
