Description

[Liz Henry (:lizzard Please n-i to RyanVM, jcristau, or pascal)]

This bug was filed from the Socorro interface and is 
report bp-42e99446-492a-4599-9f64-99ae22141016.
=============================================================
This crash is showing up in Firefox 34.0b1, 35.0a1, and 36.0a1, only on MacOSX 10.9. It feels too early & not enough data to call it a top crash, but it is #6 for crash signatures showing up for Beta 34 at the moment with 18/723 crashes.

Looks like null+offset.
https://crash-stats.mozilla.com/report/index/eebb5931-83a6-4754-b928-66d062141010 has better stack.

This is a regression from bug 1057518.

Although this only landed on m-c recently, the fix is really simple. I'd like to get this into beta3 to assess the impact on the status of this bug as the #2 top crash on beta1 (comment 5). Can you submit an uplift request for Beta and Aurora?

No crashes in Socorro for both signatures after this fix, as it follows:

Tanvi, any idea if those are related?

Looks like these are from HTMLMediaElement.  Perhaps another null check was missed?

The latest reports still show the 18 crashes reported by Alexandra a week ago for Beta (3 and older). Does this warrant a new bug to track the remaining crashes, or should we consider this good enough for Beta?

Any thoughts on the above Tanvi?

Hi Florin,

Sorry, I was out last week and hence the delay in response.  Sounds like this is a new and different bug.  My patches didn't touch HTMLMediaElement.  Thanks!

[[SV Manager] Florin Mezei, QA (:FlorinMezei)]

Thanks Tanvi! Another check today (for the past 4 weeks) shows a rise in crashes with [@ nsINode::NodePrincipal()], but they all seem to be in HTMLMediaElement as you mentioned:
- 36.0a1 (Oct 21 builds and later) - 0 crashes
- 35.0a2 (Oct 23 builds and later) - 6 crashes (all in HTMLMediaElement) - http://bit.ly/1tiSHQ2
- 34.0b - 432 crashes - http://bit.ly/15wJXAV
   * Beta 3 = 3 crashes
   * Beta 4 = 15 crashes
   * Beta 5 = 4 crashes
   * Beta 6 = 5 crashes
   * Beta 7 = 12 crashes
   * Beta 8 = 25 crashes
   * Beta 9 = 122 crashes
   * Beta 10 = 91 crashes
   * Beta 11 = 155 crashes (all in HTMLMediaElement)

The remaining crashes are tracked in bug 761485. Marking this one as verified
