Bug 2139552

Proposed as a Blocker for 37-final by Fedora user lruzicka using the blocker tracking app because:

 And one more basic functionality.

I don't have a gitlab account.  I don't know anything about gnome-calendar, but here is a guess about what is wrong from the comments on the bug.

In one of the Gitlab comments on the bug, someone said "The duplicates disappears if we kill /usr/bin/gnome-calendar --gapplication-service". 

So, gnome-calendar is running as a service, ane when the user closes the app, the service doesn't shut down.  From what happens in the bug, the service must  keep a list of all the events and that list is used by the app to draw the events in week mode.  When the app is restarted and connects to the service, the bug would happen if the app reloaded the events from the calendar database and added them to the service.  The service keeps what was there the last time the app closed, so it would get an additional copy of each event (from the external database) each time the app restarted (like in the bug).  

If you stop the service (reboot,r log out of the linux user, or kill the service), and then start gnome-calendar, it would be back to showing just one entry for each calendar event.  And the extra copy would be added again every time the app was stopped and restarted.

If that's it, it would be easy to fix for someone who knew the code.

Please ignore my comment.  I got a gnome gitlab account and commented there.

I tested the new RC iso (Fedora-Workstation-Live-x86_64-37-1.7.iso) and i can't reproduce the bug. This compose have gnome-calendar-43.1-3.fc37

Discussed at the 2022-11-07 blocker/FE review meeting: https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2022-11-07/ . This was rejected as a blocker due to the fairly moderate impact of the bug (the events are *there*, just...multiple times), and the apparent difficulty in clearly reproducing it. We decided these factors meant it's not a clear "basic functionality" failure.
