[Tracking Requested - why for this release]: This is a low volume crash that appears to have started in Firefox 45. There have been 378 reports of this crash over the last week in Firefox 45.0.2 which ranks it around #212. The crash seems to be predominantly reported on Windows 7 32-bit, although not exclusively and has no strong correlation to any particular graphics vendor/device/driver combination. Unfortunately I'm still having authentication issues so I am unable to get URLs at this time.
urls: overwhelmingly Facebook. Too late to fix in 46 unless it is a major issue/dot release driver. Let's track this for 49 and try to find an owner to investigate. Jeff, Morris, is this something one of you could look at?
Milan can you help find an owner for this crash bug?
Peter, do you have somebody that could take a look at this soon? I imagine a regression from bug 1221822.
Looks like the SourceSurface might be null. Morris, please help to check. https://hg.mozilla.org/releases/mozilla-release/annotate/078baf501b55/dom/canvas/TexUnpackBlob.cpp#l314

Hi Milan, should we consider uplifting this crash fix to Beta47, Aurora48? Thanks!
