title: Automapper: "Missing type map configuration or unsupported mapping"
body: <p>AssertConfigurationIsValid Passes, and the object being tried is fully populated, but I get the error on the first Map request called.</p>
  
  <p>I'm trying to map</p>
  
  <pre><code>Survey ToLoad = Mapper.Map&lt;Survey&gt;(U);
  </code></pre>
  
  <p>I'm initializing automapper with the code below.</p>
  
  <pre><code>//Lots of other Maps
  Mapper.Initialize(cfg =&gt; cfg.CreateMap&lt;User, SMUser&gt;()
        .ForMember(t =&gt; t.AccountType, s =&gt; s.MapFrom(so =&gt; so.AccountType != null ? so.AccountType : String.Empty))
        .ForMember(t =&gt; t.Username, s =&gt; s.MapFrom(so =&gt; so.Username != null ? so.Username : String.Empty)));
  
  
  Mapper.Initialize(cfg =&gt; cfg.CreateMap&lt;SurveyMonkey.Containers.Survey, Survey&gt;().ForMember(t =&gt; t.AnalyzeUrl, s =&gt; s.MapFrom(so =&gt; so.AnalyzeUrl != null ? so.AnalyzeUrl : String.Empty))
