EUnit Assert message can't have braces in it

Discovered this in converted unit tests for my JSON framework.

This, in an Echoes test project:

import RemObjects.Elements.EUnit

let lTests = Discovery.DiscoverTests()
Runner.RunTests(lTests, withListener: Runner.DefaultListener)

public class MyTests: Test
    public func AlwaysPass()
        Assert.AreEqual(1, 2, "Some message with some json { 'hello': 'world' }")


MyTests started
!> Exception of type RemObjects.Elements.RTL.FormatException on thread 0001 ()
!> Message: Input string was not in a correct format (686.1 KB)
