Description Remy Suen CLA 2012-01-05 13:13:37 EST 
CDT contributes tool items to the 'Debug' view. When the view gets closed, errors will start being logged repeatedly. The snippet below will reproduce the problem.

<extension
    point="org.eclipse.ui.menus">
  <menuContribution
      locationURI="toolbar:org.eclipse.debug.ui.DebugView?after=threadGroup">
    <command
        commandId="org.eclipse.ui.file.save">
      <visibleWhen>
        <with variable="activeWorkbenchWindow">
          <instanceof value="org.eclipse.ui.IWorkbenchWindow">
          </instanceof>
        </with>
      </visibleWhen>
    </command>
  </menuContribution>
</extension>
