Is it possible that toolbox_web_contents_ being set in DevToolsWindow somehow
affects behavior of the Update* routines?
Consider doing the following
WebContents* toolbox_web_contents = toolbox_web_contents_;
Update*();
if (toolbox_web_contents)
  delete toolbox_web_contents;

+    delete toolbox_web_contents_;
+
   DevToolsWindows* instances = g_instances.Pointer();
   DevToolsWindows::iterator it(
       std::find(instances->begin(), instances->end(), this));
