Can't set xticklabel

Bug report for Octave 3.2.0 configured for i686-pc-linux-gnu

Description:
-----------
% The following short example script

x = 0:0.1:10;
y = sin(x);

xtick = 0:pi:10;
xticklabel = [" 0 "; " pi"; "2pi"; "3pi"];

plot(x,y)
set(gca, "xtick",xtick, "xticklabel", xticklabel);

%END

The script above generates the errors listed below
in octave 3.2.0, 3.2.2, but not in 3.0.5.
I'm not sure if something changed in the syntax
but I think it is a valid Matlab code.

There is no problem if xticklabel is a single
string (like xticklabel="pi"), only when it is
a table of strings.
