Error calling SetupAllProperties for Mock<IDataErrorInfo>

[GoogleCodeExporter]

What steps will reproduce the problem?
 [TestFixture]
public class FooTests
{
        [Test]
        public void TestCase()
        {
            var mock = new Mock<IDataErrorInfo>();

            mock.SetupAllProperties();
        }
}

What is the expected output? 
no errors

What do you see instead?

This still happens with 4.0.812.4. The cause seems to be that IDataErrorInfo 
defines 
an indexer, which is implemented as a property whose get/set methods take a 
parameter.

I would propose modifying Moq.Extensions.CanOverrideGet() to read

    return getter != null && getter.IsVirtual && !getter.IsFinal && 
(getter.GetParameters() == null || getter.GetParameters().Count() == 0);

I've also written this regression test which fails without this modification 
and 
passes with this modification:

        #region #205

        public class _205
        {
            public interface IIndexer
            {
                string this[string param] { get; }
            }

            [Fact]
            public void Test()
            {
                var mock = new Mock<IIndexer>();
                Assert.DoesNotThrow(() => mock.SetupAllProperties());
            }
        }

        #endregion
