Resharper Exception rethrow possibly intended

Consider this method (pardon the sad attempt at Chuck Norris humor :) ):

public class ChuckNorrisException : Exception
{
    public ChuckNorrisException()
    {
    }

    public ChuckNorrisException(string message)
        : base(message)
    {
    }

    public ChuckNorrisException(string message, Exception cause)
        : base(message, cause)
    {
    }

    protected ChuckNorrisException(SerializationInfo info, StreamingContext context)
        : base(info, context)
    {
    }
}

static void ExceptionTest(double x)
{
    try
    {
        double y = 10 / x;
        Console.WriteLine("quotient = " + y);
    }
    catch (Exception e)
    {
        e = e is DivideByZeroException ? new ChuckNorrisException("Only Chuck Norris can divide by 0!", e) :
            e;
        throw e;
    }
}

In resharper, I get a warning on the "throw e" line saying "Exception rethrow possibly intended". But obviously in this case that's not the intention, since e could be wrapped in ChuckNorrisException, and if I just use "throw", that wrapped exception wouldn't get thrown.

I know I can suppress the resharper warning, but then it will be turned off for all scenarios if I'm not mistaken. I just wondered if anybody else had encountered this. The only workaround I've found is to make another exception variable (e2, for example), and throw that. That may be the best I can do here. Seems like resharper could detect this issue though and be smart enough to know that if e is modified, then throw e is ok.

Thanks.

[EDIT] Sorry, I forgot a step. Before the throw, I need to log the exception, so I can't just do:

e = e is DivideByZeroException ? new ChuckNorrisException("Only Chuck Norris can divide by 0!", e) :
            e;
throw e;

I have to do:

e = e is DivideByZeroException ? new ChuckNorrisException("Only Chuck Norris can divide by 0!", e) :
            e;
LogException(e);
throw e;
