Details:

        I am running Octave 4.0.0 on Linux Mint 18.3 ‘Sylvia’ which is in turn
running on an HP Compaq Elite 8300.

I created a .jpg file using LibreOffice Writer called LibreOffice_test.jpg
(Attached)

In Gnu Octave I did the following and got the folowing result upon left
clicking the mouse in the figure window.

>> LO_im = imread('LibreOffice_test.jpg');
>> imshow(LO_im)
>> ginput(1)
error: invalid conversion of uint8 matrix to Matrix
error: called from
    ginput at line 85 column 7
error: invalid conversion of uint8 matrix to Matrix
error: called from
    ginput at line 85 column 7

I don't understand how this could be wrong.
    Thank you for looking at this.
        Mark
