Found a couple other signatures seemingly related to this issue.

[Tracking Requested - why for this release]: Nominating to track since this is such an explosive crash.

As a note, this currently has 474 reports in the last week with combined signatures which makes this the #1 topcrash in Firefox 49 by far, accounting for 13.76% of the overall crash volume. Based on data it looks like this might have started with Nightly 20160512030253 which would assume the following pushlog.

We can track this for now, but comments in https://groups.google.com/a/mozilla.com/forum/#!topic/projectuptime-team/or0j02gUxm0 indicated that there is a symbols issue going on, so until that gets fixed we may not exactly what these crashes are (and the signatures will change).

This is probably just invalid then. The signatures here happened on one build each.  No reports since the fix in bug 1272278 landed.  Hopefully these shutdown hangs are getting picked up in proper signatures.

I can leave this open until we confirm they are - and I also pinged ted in the other bug about reprocessing the crashes to get the right signatures.

Closing this one out as invalid - as twalker mentions in Comment 4 these signatures stopped happening - and after reviewing crash stats today things look good - so I think we are OK here.
