title: Emgu CV "Emgu.CV.Util.CvException" when using GaussianBlur with size>3
body: <p>I have a very strange problem when using Emgu CV's gaussian blur functionality. Blurring an image works fine when I use a kernel size of 1-3, but when I use a larger size, my application exits with the following message:</p>
  
  <p><code>Exception thrown: 'Emgu.CV.Util.CvException' in Emgu.CV.World.dll</code></p>
  
  <p>I'm working in Visual Studio, and it doesn't even give me the standard exception popup. It just exits and throws me back to the editor.</p>
  
  <p>This is the code I've tried:</p>
  
  <p><code>CvInvoke.GaussianBlur(image, image, new Size(4, 4), 0, 0);</code></p>
  
  <p><code>image._SmoothGaussian(4);</code></p>
  
  <p>Both examples give the same results.</p>
