-- Information about the crash:
I had just rebooted my machine earlier this morning after installing updates. After logging in I started doing the usual stuff (opening/positioning windows) I do after rebooting. I saw the Discover tray icon indicating available (Flatpak) updates so I clicked it to see what was available. 
I'm unsure about the exact order of the following event as they happened close together.
When I clicked the tray icon Discover opened, but was not showing any updates (list was blank, still loading I guess). When/Before they showed up in the list plasmashell crashed and was automatically restarted.

The reporter is unsure if this crash is reproducible.
