Oddness with errorbar after another plot

[Brendan Drew]

I'm not sure if this has been fixed (I'm in the process of rebuilding from CVS that I got earlier today), but I've included a bug report just in case. 

--------
Bug report for Octave 2.9.4 configured for i686-pc-linux-gnu

Description:
-----------

Even with explicitly specifying hold off, errorbar seems to forget to clear the 
previous plot. If it makes any difference, I'm using SuSE 10.0

Repeat-By:
---------

X = (0:0.01:1)*2*pi;
Y1 = cos(X).^2+0.25;
Y2 = sin(X);
plot(X,Y1,';Y1;');
% produces plot1.png, see attached

hold off;
errorbar(X,Y2,Y1,';Y2 +- Y1;');
%produces plot2.png, see attached

Fix:
---

I don't know of a real fix; however, closing the current figure and opening a 
new one seems to be a work around (the downside is the fact that my machine 
becomes unusable while gnuplot windows keep on popping up and taking focus away 
from whatever I was working on)
