Bug in imrotate.m?

I am trying to rotate a square image by 20 degrees but imrotate crashes with an error in padarray. The test function is

function test_imrotate

x=-5:0.05:5;
y=-5:0.05:5;
[X,Y]=meshgrid(x,y);
G=exp(-X.^2-(3.*Y).^2);
G20=imrotate(G,20);

and this will give

>> test_imrotate

Error using padarray Too many input arguments.

Error in imrotate (line 140) A = padarray(A,[2 2],0,'both');

Error in test_imrotate (line 7) G20=imrotate(G,20);

I am running 8.5.0.197613 (R2015a) under Linux ubuntu 14.04LTS.

Try a which -all padarray, maybe you have a different version shadowing the toolbox?
