I mentioned this in the PR but I should have restated it here, sorry...
Wolfgang authored this patch.  He is away for a month so I volunteered to post this, in case it was okay for resolving the PR as the crash is present in the 5.0 branch.
I do know Wolfgang was not really happy with it, and your questions might well be part of why that is.
The patch has been in our local version of 5.0 for a couple of weeks without obvious problems, but that is not proof that it is always okay.
