I recently installed Elmah on my instance of BE.  One error that is prevalent is an ArgumentOutOfRangeException in pingback.axd.  The stacktrace I have available is below. Is anyone else seeing this? Is it something to worry about?


System.ArgumentOutOfRangeException: Length cannot be less than zero.
Parameter name: length
   at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy)
   at BlogEngine.Core.Web.HttpHandlers.PingbackHandler.GetPostByUrl(String url)
   at BlogEngine.Core.Web.HttpHandlers.PingbackHandler.ProcessRequest(HttpContext context)

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I think I traced it down to FOAF handler not happy with empty user profile. Try to create profile for your user and it should go away (if this is the same error I ran into).
