Here is another repeatable error:
from Detail window (person view) for "X" person,
I double clicked "father" to add an existing person. (no problem)
Then I entered the person #. (no problem)
Then I clicked Repeat Recent Citations button. (no problem)
Then I selected topmost citation. (no problem)
Then I hit "OK" on Citation window, and get the following error:
