This problem has been already discussed in the upstream mailing list [1].  I
do not know how to fix it.  For now, you could try the following:

$ sudo apt-get install ttf-bitstream-vera
$ export GDFONTPATH=/usr/share/fonts/truetype/ttf-bitstream-vera
$ octave
octave:1> figure;
octave:2> plot (1:2, 1:2);
octave:3> xlabel ('Label X', 'Fontname', 'Vera');
octave:4> ylabel ('Label Y', 'Fontname', 'Vera');
octave:5> title ('Title', 'Fontname', 'Vera');
octave:6> legend ('Blue Line');
octave:7> print('/tmp/testcase.png');
