Editing a Rule in an existing custom filter generates an error

This was in Gramps 5.2.0-rc1-77457edf0 on Fedora. Please confirm the error occurs on other Linux, Windows or macOS.

Editing the “Soundex match of People with the ” rule in an existing Person custom filter gives an error, twice. (But the editing and filter still work.)

Clicking the “Edit the selected rule” button in the Define Filter dialog shows the following console error message.
