Crash when clicking a modified Google event right after editing it (due to the preview popover)

Affected version

  • Fedora 38
  • gnome-calendar-44~rc-1.fc38.x86_64
  • gtk4-4.10.0-2.fc38.x86_64

Bug summary

If an event from a Google calendar is edited, and I click on it right after editing it, Calendar crashes or gets unresponsive.

  • The event needs to be from Google calendar (or possibly other remote source), it doesn't crash with a local calendar
  • I can edit e.g. event name or location
  • To trigger this, I have to click on the event quite quickly after confirming the change. It seems that if I click on the event before the change is submitted to Google servers and then refreshed, it triggers this problem. If I wait for a few seconds and then click on the event, it's fine.
  • There are two options, either it crashes, or the window becomes unresponsive, nothing can be clicked on, and it can't be closed either (gnome-shell doesn't invoke the unresponsive window dialog, so the only option is to send sigterm to the process, to close the window).

Steps to reproduce

  1. Create an event in a Google calendar
  2. Edit the event name
  3. Immediately click on the event again

Relevant logs, screenshots, screencasts etc.
