-- Information about the crash:
Whenever you hover over one application on KDE, it shows a preview of the
application window, so when you move your mouse over different programs to
select one of them, the behaviour (as I understand) is that the preview is
shown and then closed very shortly and it's probably freeing some objects right
before some code tries to access it.
This problem happens more often when you move your cursor very quickly over the
application icons, but I've seen it happening when moving the cursor very
slowly as well. I'm saying in the past because this problem was very apparent
in the early months of KWin Wayland implementation, and now it's back again
haunting us.
The reporter is unsure if this crash is reproducible.
