Details:

The following unit test for function grayslice in package image is failing
randomly:


>> test grayslice
***** assert (grayslice (im2uint8 (I2d), 3), uint8 (test_grayslice_scalar
(I2d, 3)))
!!!!! test failed
ASSERT errors for:  assert (grayslice (im2uint8 (I2d), 3),uint8
(test_grayslice_scalar (I2d, 3)))

  Location  |  Observed  |  Expected  |  Reason
   (2,8)          1            0         Abs err 1 exceeds tol 0 by 1


In the test text


### FIXME investigate why this sometimes fails
%!assert (my_grayslice (im2uint8 (I2d), 3), uint8 (test_my_grayslice_scalar
(I2d, 3)))
%!assert (my_grayslice (im2uint16 (I2d), 3), uint8 (test_my_grayslice_scalar
(I2d, 3)))
