On octave 4.0.0 on windows and Cygwin, there seem to be no problem:
octave:1> graphics_toolkit gnuplot
octave:2> gnuplot_binary ("somejunk")
octave:3> plot(1:3)
error: popen2: process creation failed
error: called from
__gnuplot_open_stream__ at line 30 column 40
__gnuplot_drawnow__ at line 72 column 19
octave:4>
After error messages, octave prompt represented normally.
