title: umbraco examine index rebuild exception
body: <p>I am trying to rebuild my internal index. I am using tools such as the <a href="http://our.umbraco.org/projects/developer-tools/examine-dashboard" rel="nofollow">examine dashboard</a> that clear the index and re-run indexing.</p>
  
  <p>For some reason this always results in an exception and I am left with no index. This is probably due to "ghost" content in the database or something like that.</p>
  
  <p>This is the exception:</p>
  
  <pre><code>[SqlHelperException: Umbraco Exception (DataLayer): SQL helper exception in ExecuteXmlReader]
     umbraco.DataLayer.SqlHelper`1.ExecuteXmlReader(String commandText, IParameter[] parameters) in C:\tfs\xo\rotiseme.xo.gr\Indice\umbraco_4.7.1\umbraco\datalayer\SqlHelper.cs:272
     umbraco.cms.businesslogic.web.Document.importXml() +185
  </code></pre>
  
  <p>Any ideas how I can recover from this?</p>
