            Bug ID: 141863
           Summary: previousLinePosition & nextLinePosition call
                    editingIgnoresContent without checking if parentNode()
                    is NULL
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML Editing
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: d_russell at apple.com

editingIgnoresContent() expects a non null parent node in order to behave correctly and previousLinePosition & nextLinePosition aren't performing that check. This manifests regularly when navigating via cursor with accessibility enabled. (Not an accessibility bug, just happens to encounter it.)
