Assertion message formatted poorly by PropertyConstraint

[Peter Strøiman]

When I place an EqualConstraint with a tolerance inside a PropertyConstraint, the error message fails to format the tolerance.

So this is only a formatting issue, the test gives the correct result.

The following code reproduces the bug.

This was observed in NUnit version 2.5.5.10112
The code is compiled in Visual Studio 2010 targeting .NET 4.0 framework

 public class C { public decimal d { get; set; } }

 [TestFixture]
 public class T
 {
  [Test]
  public void PropertyConstraintTest()
  {
   var c = new C { d = 100.0m };
   // Write the error message
   // Expected: 105m +/- 0.1m
   // But was: 100m
   //Assert.That(c.d, new EqualConstraint(105m).Within(0.1m));

   // Writes the error message
   // Expected: property d equal to 105m +/- <NUnit.Framework.Constraints.Tolerance>
   // But was: 100m
   Assert.That(c, new PropertyConstraint("d", new EqualConstraint(105m).Within(0.1m)));

  }
 }
