I'm pretty sure this will fix it.

Still, I'd really like to have a look at frame tree / display items
when this crash occurs.

It's not completely minimized yet, working on it.

This is more or less minimized.

Thanks Martijn!  I can reproduce the crash, investigating...

Frame dump

It's a display item for a fixed pos. frame.  Hmm, I didn't expect that there,
I thought those would end up on their containing block's display lists.
Oh well, the attached null-check should fix it.

Hey, no need to be rude!  FYI, comments like that *never* helps.

Implying that he is rude...
Implying that you not spam this bug (like me now)...

Adding Mac signature so it gets picked up in crash stats.
