Yes, it is the same plotting issue. Without plotting, it works:
[gm, pm, w_gm, w_pm] = margin (H)

I forgot to fix margin when I updated the other plotting commands. However, 
margin is a bit more difficult to fix. I know a hack, but maybe I find a more 
elegant solution.

BTW: Could you please do me a favour and test the following code?

semilogx (1:10, 1:10)
ax = [1, 10, NaN, Inf]
axis (ax)
grid on
title ("title")
xlabel ("xlabel")
ylabel ("ylabel")

What's happening? I need that info for a bug report:

(IIRC you are using ubuntu 10.10 with octave 3.4.3)
