It looks like in bug 764125 we added a delete of mSurface, but if Init fails it is never set: > http://hg.mozilla.org/mozilla-central/file/9e3d649b80a2/gfx/2d/DrawTargetCairo.cpp#l511 Which would call cairo_surface_destroy on uninitialized memory. I'm not sure that this can actually happen or is just a red herring though, paging @nrc

Hi, I'm no longer working on graphics stuff and the DrawTargetCairo stuff was so long ago I don't think I can remember anything useful here. Probably the best person to ask about this is Bas.

It happened again: https://crash-stats.mozilla.com/report/index/8247e49a-f8b4-4e2a-8455-969492140930 This time I hovered over the icon in the taskbar and noticed it was showing a spinner for the thumbnail of every tab except for the one in the window that I currently had opened. After waiting a second or two, I hovered over one of the tabs with the loading spinner for a thumbnail and it crashed.

@roc Is this a dupe of bug 1071079 / or bug 1072847? (I've not access to the later)
