title: Custom asp.net profile provider cause intermitent exception
body: <p>I got a asp.net application hosted by Godaddy. In this app I have a custom profile provider. Sometime, an ASP.Net error message prompt and Say: "<code>Unable to cast object of type 'ProfileCommon' to type 'ProfileCommon'</code>"</p>
  
  <p>The error appear at a random time and vanish when a modification to the web.config file is made (maybe because of the rebuild of the application ?).</p>
  
  <p>On my development computer and my staging server the error did not show up.</p>
  
  <p>Do someone already see this error?</p>
