           Summary: Cairo GraphicsContext null-pointer dereferences
                    (segfaults on many pages on Wikipedia and other sites)
           Product: WebKit
           Version: 522+ (nightly)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: m at ni.ac.nz


Cairo's GraphicsContext doesn't set paintingDisabled to true if passed a null
PlatformGraphicsContext. This results in many null-pointer dereferences.

Other platforms such as Qt do set paintingDisabled to true if passed a null
PlatformGraphicsContext.

A patch is forthcoming.
