I have gotten a couple of these in the recent nightly. I did not get any of these before E10S was enabled so it could be related to that.

This may or may not be the same bug, if not then it will likely need to be split off. This was suggested by the crash reporting system though.

No crashes for either signature in the past week, resolving.
