TestFixtureTearDown in static class not executed

[rstarkov]

Here's an example:

    [TestFixture]
    public static partial class Tests
    {
        [TestFixtureSetUp]
        public static void Init()
        {
            Console.WriteLine("INIT");
        }

        [TestFixtureTearDown]
        public static void Cleanup()
        {
            Console.WriteLine("CLEANUP");
        }
    }

Init() gets executed but Cleanup() does not.

Could it be that this code, in NUnitCore\core\TestSuite.cs:

        protected virtual void DoOneTimeTearDown(TestResult suiteResult)
        {
            if ( this.Fixture != null)

should actually look like this:

        protected virtual void DoOneTimeTearDown(TestResult suiteResult)
        {
            if ( this.FixtureType != null)

which would make it the same as DoOneTimeSetUp?
