I suspect it is because (with early experiment) that CreateNotify and DestroyNotify X events are not being received, so that destroyed window pointers are being accessed, leading to segfault.

If this hypothesis is true, then it would also explain (and eventually fix) how we sometimes don't have thumbnails for newly created windows.
