Alex, did you experience this crash yourself? Do you have steps to reproduce? Or did you file this because it's a topcrash or recent regression?

¡Hola Benjamin!

This was sitting on about:crashes for one of my systems so I figured I shall file a bug as there wasn't one that matched.

Unfortunately I do not have steps to reproduce the crash.
