Weird... I can't duplicate this with 3.0.2+ or 3.1.51+ (Sorry I don't 
have 3.0.2 to check) and so I suspect that either its already been fixed 
(though I don't see a patch addressing this) or its some particular 
issue with your installation. Try the command

figure(1); clf; title('ABCDEFGHIJKLMONPQRSTUVWXYZ'); xlabel('a \in [0,1]');
drawnow ("x11", "/dev/null", false, "debug.gp")

This will create a file debug.gp with the commands that Octave sends to 
gnuplot. You can then do "load debug.gp" in gnuplot to get the same 
result. It might be easier to debug your issue using this file than 
modifying Octave itself. In any case maybe you could send the file here 
for info.
