Comment 9 for bug 1640542

so trying to get a clean stack trace, I repeatedly saw indication of dandling manager pointer,

I had the crashes actually in the main view too,

the specific context that seems to make it more easily reproducible with omgubuntu is the amount of frames that it contains and the amount of frame reloads/redirections that happen there,

this is the amount of scripts context being freed during a load:

this is without any navigation (the number indicate the world id, 0 being the main world),
