If you can produce a simple example so that I (or someone else) can duplicate 
what you're seeing, then we can file a bug report and provide a work around for 
you.

Running the developers sources for Octave 3.6.x,  and with either the gnuplot 
and fltk graphics toolkits, the following works for me (the legend and plot box 
do not overlap)

        clf
        plot(1:10, 1:10);
        title("a very long label can sometimes cause problems");
        legend({"hello world"}, "location", "northeastoutside");

If I add ...

        legend right

There is still no overlap between the legend and plot box.
