Object .Gjs_AppIndicatorIconActor__1 (0x5582a2e9b240), has been already finalized. Impossible to set any property to it

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

Hi Sebastien. It seems to be reproducible, but I don't know how to do it. I see several events in my log today. One clue I see is that there is a gnome-software message as well as the gnome-shell traces. I then ran gnome-software. I see that it last checked at 6:16. And in the log, there's one of these traces at 6:16.

Unfortunately, starting gnome-software and asking it to refresh didn't create another stack trace.
