Unity Interception

I am using Unity Interception to handle logging.  I would like to use the IMethodInvocation target property, but it causing a stackoverflow exception.  It seems that by referencing this property, it is intercepted again.

How can I prevent this? 

I am able to reference other properties, such as MethodBase without this behavior. 

Any Ideas?

public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
{
        if (_log_Debug)
       {
           // this line is not intercepted
          var y = input.MethodBase;
   
           // the line below is intercepted again...
            var x = input.Target;
         }
    ...
