This appears to be a regression of http://code.google.com/p/chromium/issues/detail?id=79739 / https://bugs.webkit.org/show_bug.cgi?id=58821. However, the changes to GraphicsContext3DSkia::getImageData() made then seem to be intact, suggesting it's a similar bad cast in some other place.

At least three callers are using Image::isBitmapImage() as RTTI and casting an Image to a BitmapImage so they can call the functions on it. Although BitmapImageSingleFrameSkia is implemented as a bitmap, it doesn't have all the other baggage that has accreted around BitmapImage (multiple animation frames).
