It's currently #1 top crasher in today's build where it appeared for the first time. The regression window is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=46804c31366b&tochange=6489be1890c0 It's probably a regression from bug 771251 as there are no Flash crashes in this build.

Comment on attachment 641941 [details] [diff] [review] Null-check, rev. 1 Review of attachment 641941 [details] [diff] [review]: ----------------------------------------------------------------- Kind of a bummer, I guess we'll just orphan these files? We should investigate why this winds up as a topcrash, presumably there must be some shutdown plugin topcrash.
The outcome of IRC discussions is that this is a common shutdown crash that bc is seeing, and that this patch won't make it any worse.
Comment on attachment 641941 [details] [diff] [review] Null-check, rev. 1 Bug caused by (feature/regressing bug #): bug 771251 User impact if declined: crashes (assuming we take bug 771251, which we really need for correct Flash crash reporting Testing completed (on m-c, etc.): landed on m-c, should be verified by crash-stats tomorrow Risk to taking this patch (and alternatives if risky): no risk (all the risk is in bug 771251)
Tracking for 15 which I think is what you're looking for here now, post merge.
