Details:

Hi, 
I am running the 3.8.1 version packaged on Debian (I tried the develoment
source, but both default and stable branch didn't build).

Consider the following code:
imagesc(eye(100)+1);
h=colorbar()
set (h, 'YScale', 'log')

After the call to colorbar(), the colorbar() is correct. Resizing it as
logarithmic results in a white colorbary (at least with the fltk backend). 
I am attaching two saved images, the correct one after the call to colorbar
and the incorrect one after the rescaling. Please note that the scaling is
adapted to what seems to be correct, but the colorbar is losing all colors.
