Crashes/hangs on startup after bookmarking my home address

When I launch a freshly installed GNOME Maps (either from Debian testing/unstable or from Flathub), Maps works fine. Then I search for my home address and bookmark it. Once I done that, I cannot start Maps any more; it produces an error during startup and the interface does not appear. (This is particularly confusing when starting it from GNOME Shell as it seems to be starting but thing happens.)

The reported error is:

$ flatpak run org.gnome.Maps

If I remove <local-dir>/gnome-maps/places.json, I can start it again.
