No crashes seen on nightly 65 since the build from 11-14.

Comment 2

[Eitan Isaacson [:eeejay]]

This code has changed quite a bit. Might be worth investigating if something resurfaces, until then shall we close this?

Comment 3

[Marcia Knous [:marcia]]

Yes, I think for now we can close this as works for me, and reopen if it resurfaces.
