I would be you, I would check whether you don't have any home-made script named roots in your MATLAB path.
If you have no idea where it could be, maybe run it first once with:
roots;
Then, maybe, the output of the script would give you some hints.

This may be the case indeed. The in-built Matlab "roots" works perfectly
p=[1 0.45 0 -0.0133 -0.08 0 0.016];
>> roots(p)
ans =
-0.0941615598738199 + 0.564658612501628i
-0.0941615598738199 - 0.564658612501628i
-0.576214580558998 + 0i
-0.474450496188147 + 0i
0.394494098247393 + 0.151545050491967i
0.394494098247393 - 0.151545050491967i
