TypeInitializationException when using Nancy.Testing with NUnit test runner

I am writing a test using version 1.2 of Nancy and Nancy.Testing via NuGet. My test is written with NUnit 2.6.4 and looks like this:

[Test]
public async Task ShouldReturnSuccessfullyAuthenticatedUser()
{
    // arrange
    var request = CreateRequest();
    var userDocument = CreateUserDocumentFrom(request);
    await userRepository.AddAsync(userDocument);

    // act
    var response = browser.Post(Paths.Login, with => with.JsonBody(request));

    // assert
    response.StatusCode.Should().Be(HttpStatusCode.OK);
}

I have this exception:

System.TypeInitializationException : The type initializer for 'Nancy.Bootstrapper.AppDomainAssemblyTypeScanner' threw an exception.
  ----> System.IO.DirectoryNotFoundException : Could not find a part of the path 'E:\myProject\bin\Debug\bin\Debug'.

And I think there's something wrong when using Nancy.Testing with NUnit, because the equivalent test in xUnit runs just fine.

It looked like NUnit was tryging to automatically add bin\Debug to the bin path. The way I solved it is to specify explicitly what kind of bin path to use. Here is the .nunit project file:

<NUnitProject>
  <Settings activeconfig="Debug" />
  <Config name="Debug" binpathtype="Manual">
    <assembly path="bin/Debug/MyUnitTests1.dll" />
    <assembly path="bin/Debug/MyUnitTests2.dll" />
  </Config>
  <Config name="Release" binpathtype="Manual">
    <assembly path="bin/Release/MyUnitTests1.dll" />
    <assembly path="bin/Release/MyUnitTests2.dll" />
  </Config>
</NUnitProject>

The XML attribute NUnitProject\Config\binpathtype had previously a value of Auto. When I changed it to Manual as above the exception was gone and my tests ran successfully.
