Status in NUnit V2 Test Framework: Triaged

Bug description:
I'm upgrading from NUnit framework 2.4.8 to 2.5.2.

Now, a StackOverflowException occurs when calling Assert.AreEqual(object,object,string).
The arguments are actually equal.
The object is IEnumerable and directly contains itself.

Work around: use identity instead of equality comparison.

Using NUnit 2.5.2.
