           Summary: [GTK] GTK's DRT not to log events for already defunct
                    objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: msanchez at igalia.com


If an AtkObject has emmitted the 'state-change::defunct' function it means it is not a valid object anymore, so we should not do anything about it, like trying to retrieve its name and role for loggint purposes, which is what printAccessibilityEvent() in Tools/DumpRenderTree/gtk/AccessibilityCallbacks.cpp does.

Filing this bug now since recent changes in the repository (r105253) unveiled that not controlling this situation could lead to DRT segfaulting in some tests (like platform/gtk/accessibility/combo-box-collapsed-selection-changed.html, which is skipped at the time of this writing).
