           Summary: [chromium] DRT crash in fast/canvas tests w/accel 2D
                    canvas due to NULL DrawingBuffer
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kbr at google.com

The following test cases in fast/canvas are failing in DRT when run with --enable-accelerated-compositing --enable-accelerated-2d-canvas due to a NULL m_drawingBuffer in CanvasRenderingContext2D. The reason is that drawingContext() is NULL when the CanvasRenderingContext2D is created, so the drawing buffer is never initialized.
