This looks like a problem with an Octave Forge package, not a bug
in Octave. The correct place to report this problem is the
Octave Forge mailing list, octave-dev@lists.sourceforge.net.

A copy of this update to the bug report is being sent to that
list so that they are aware of it. Please follow up there.

I have installed image toolbox 1.0.10, and found that bwfill is not working for filling holes. Here is a quick test

dat=zeros(60);
theta=0:pi/360:2*pi;
ix=20*sin(theta)+30;
iy=20*cos(theta)+30;
dat(sub2ind(size(dat),floor(ix),floor(iy)))=1;

figure
imagesc(dat)
dat2=bwfill(dat,'holes');
figure
imagesc(dat2)

the same script works perfectly in matlab.
