I don't see this happening with the 4.3.0 appimage. Is it reliably repeatable? Have you installed from the Arch repository or are you using the appimage?

If it was repeatable, I'd suggest that you used the appimage to see if that fixed the problem. Given that you have a backtrace, I suggest that you leave this as Reported and see if anything happens or anyone else has a similar problem.
