title: umbraco 6 home errors out on appharbor
body: <p>Here's the scoop. I created an Umbraco 6 MVC app locally (pointing to a Yocto shared SQL server appharbor add-on), installed it and it runs fine. I can add doc types, create content, blah, blah.... locally.</p>
  
  <p>Then I pushed the solution to the AppHarbor GIT repo and it built and deployed successfully. However, to my surprise, I get a lovely YSOD and the following error when I try to go to the home page:</p>
  
  <blockquote>
    <p>[NullReferenceException: Object reference not set to an instance of an
    object.]    Umbraco.Web.UmbracoModule.BeginRequest(HttpContextBase
    httpContext) +13    Umbraco.Web.UmbracoModule.b__5(Object
    sender, EventArgs e) +253<br>
    System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
    +136    System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously) +69</p>
  </blockquote>
  
  <p>The app's errors logs report this error is occurring for the following request paths:
  /
  /favicon.ico</p>
  
  <p>This one has me stumped. Any thoughts?</p>
