Looking at the exception, this would probably occur any time the message 
contains braces. The simplest fix would be to not run it through string.format 
in no arguments parameters are present.

I can't reproduce this :(

The tests fail, but not because of a FormatException. We did have problems 
before, when the string was too long.

What version can you not reproduce this in? What runner? The tests are supposed 
to fail, but should report the exception. MBunit 3.3.1 via Resharper. Original 
issue was  3.3.0 via echo or icarus.

[Test]
public void ShortMessageWithBraces()
{
    Assert.IsTrue(false, @"Hello {{{");
}

This is not a critical problem.
