May be related to bug 1466406. In particular, if we get away without crashing from there, we may crash around here without too much trouble I'd think.

Comment 2

[Emilio Cobos Álvarez (:emilio)]

Oh, this is beta, let's forget that. So this is only on a single build and also on a single CPU model, interesting...

Comment 3

[Marcia Knous [:marcia]]

This is starting to show up in 61 b11, so for now it is not limited to a single beta build.

[Mats Palmgren (inactive)]

I looked at 10 or so of the crash stacks and they were all completely bogus.
This crash could be just about anything; not necessarily style system at all.

Seems to have dropped off.

Closing because no crash reported since 12 weeks.
