A crash occures if I try to write an image to the harddisk using imwrite:

octave:1> imwrite(uint16(zeros(100,100,3)), "test.tiff")

----------------------------------------------------------------

If there was an imread before everything is fine:

octave:1> imread("example.tiff");
octave:2> imwrite(uint16(zeros(100,100,3)), "test.tiff")
octave:3>

The same behavior occures in an freshly installed ubuntu linux - also octave
3.2.4.
