Jens, I looked at your code and I don't know if this makes a difference, but I think the line data = d_resamp(256:1792) should be substituted by data = d_resamp(257:1793) since in an N=2m point FFT the DC is the m+1-st component after fftshift (in our case it is the 1025-th component).
I still believe that ftaer correct frequency compensation the picture should look like an unrotated QPSK, so my bet is that there is something wrong with the frequency correction...
