I checked changes after pre-release of 5.0.6 and found that
the change


2017-03-08  Ethan A Merritt  <merritt@u.washington.edu>

    * src/qtterminal/QtGnuplotEvent.h: Move new enum GEPID (2017-02-25) to
    end of enum list rather than in the middle.  Otherwise the gnuplot_qt
    built for 5.0.6 is incompatible with gnuplot executables 5.0.0-5, which
    makes comparison of multiple versions to debug things harder than it
    needs to be.  If the new event is at the end, all earlier gnuplot 5.0.x
    versions can share gnuplot_qt 5.0.6.

prevents gnuplot_qt.exe to start on windows.

I do not have enough knowledge so that I do not know why this change causes 
trouble on qt terminal for windows.
