Error when using gurobi to solve SOCP

I’m trying to solve the following SOCP problem:
B(kn,n), Nin(n,3), lambda(1,1), p=ones(kn,1) are known, t(kn,1) and Nout(n,3) are variables to optimize

min p'*t s.t. 
         norm((B*Nout)(i,:))<=t(i)
         norm(Nout(i,:)-Nin(i,:))<=lambda  

the code I use is:

cvx_clear;
% cvx optimization
cvx_begin 
    % cvx_solver sedumi
    cvx_solver gurobi 
    p=ones(kn,1);
    variable Nout(n,3)
    variable t(kn,1)
    minimize(p'*t);
    subject to
        sum((Nout-Nin).^2,2)<=lambda;
        sum((B*Nout).^2,2)<=t;
cvx_end

It can be solved by sedumi without problem. However, when I try to use gurobi for better performance, cvx give me the following error message:

Barrier solved model in 63 iterations and 266.48 seconds

Warning: to get QCP duals, please set parameter QCPDual to 1

The chances of any help are greatly improved if you post a full example including data
(even trivial ones).

[EDIT]
I get the following results running it with MOSEK 7 beta:

I’m using matlab 2012a 64bit, cvx2.0 beta and gurobi5.1, Thanks!

This is a bug, so please submit this to http://support.cvxr.com … also, can you please make sure you’re using the absolute latest build of CVX?

Yes, I am using the version Build 945. I will submit this to http://support.cvxr.com/

Great, thanks!
