Description Miguel Gomez 2018-06-22 02:02:21 PDT 
Some SVG content uses GraphicsContext::clipToImageBuffer to define a clipping from the contents of an ImageBuffer. But GraphicsContextImpl doesn't have an implementation for this method so the call cannot be delegated and recorded. Instead, cairo GraphicsContext tries to perform cairo operations while in the recording state which causes the crash.
