Follow-up Comment #1:

Confirmed.  The problem is with any null string and a simpler example is


h = plot (1:10, "o-;Legend String;");
set (h, "displayname", "")


I fixed the problem on the stable branch here
(http://hg.savannah.gnu.org/hgweb/octave/rev/a7dfb685d261).  This issue
exposed a big inefficiency on the legend code.  I have not dealt with that,
but noted it in a FIXME comment in the code.  Maybe it doesn't matter too much
because legend() isn't called a lot and the response of Octave can be on human
time scales (100's of milliseconds).
