Events are shown duplicated in the new Month view when making any changes to them (via drag and drop, event editor, other views or externally)
Create any all-day event (I didn't test time-based...), whether single-day or multi-day, and then either:
- Drag it to a different day (in any view, or with an external application), or
- Use the event editor dialog to change its start date (which also changes its end date) or any other property, or
- Use an external application to make a change that is supposed to get reflected in GNOME Calendar
Result:
- Duplicated events in the Month view.
- If you select one of the fake duplicate events and delete it, the bunch comes back after the deletion notification's timeout.

It happens consistently/solidly, not a heisenbug, so I suspect this is probably a small error/miscalculation somewhere in the new code rather than a big nastie.
