Strange. I've just tried on my machine, and get 

 sys1=tf(1,[1 3 2]) 

Transfer function 'sys1' from input 'u1' to output ...

            1      
 y1:  -------------
      s^2 + 3 s + 2

Continuous-time model.

Does the problem disappear if you put every permission under dataframe as
"rw-r--r--" ? (chmod -R 644 .)
