http://bugzilla.opendarwin.org/show_bug.cgi?id=9479

           Summary: Disassociate the inspector from the frame when it
                    detaches from its parent
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Web Inspector
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: opendarwin.org at mitzpettel.com


[This is a follow-up to bug 8672]
The current way of the Inspector observing NSWindowWillCloseNotification in
order to tell when to disassociate from the inspected WebFrame is wrong. Aside
from the fact that it doesn't track the WebFrame's WebView's window and
hostWindow as they change, a WebFrame can be deallocated while its WebView
remains in a window. For example, this crashes Safari (which is why this bug is
P1):

1. Open a frameset page.
2. Inspect an element in one of the frames.
3. Navigate to another page in the same tab.
4. Try to select a different node in the inspector.
