--- Comment #1 from Enrique Ocaña <eocanha at igalia.com> ---
These crashes come from a suggestion to use a Deque instead of the original GList during the upstreaming of the MSE code. GLists were more robust to multithreading because the links are maintained using pointers, which are atomically swappable.

What we've done downstream to mitigate this problem is to use a Vector:
