            Bug ID: 160808
           Summary: FocusController multiple dereferenced NULL pointers
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Major
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jbedard at apple.com

In FocusController, there are a number of static functions which accept references to objects and are usually called by dereferencing pointers.  Since many of the functions which call these static functions accept pointers, and in at least one case, these pointers can be NULL, these functions are undefined behavior.
