Thanks for the hint. I created a custom transformation with the first math 
tranformation of the whole transformation process:

21781,4326=INVERSE_MT[PARAM_MT["Hotine_Oblique_Mercator", \
      PARAMETER["semi_major", 6377397.155],\
      PARAMETER["semi_minor", 6356078.962818189],\
      PARAMETER["longitude_of_center", 7.439583333333333],\
      PARAMETER["latitude_of_center", 46.952405555555565],\
      PARAMETER["azimuth", 90.0],\
      PARAMETER["scale_factor", 1.0],\
      PARAMETER["false_easting", 600000.0],\
      PARAMETER["false_northing", 200000.0],\
      PARAMETER["rectified_grid_angle", 90.0]]]

This delivers wrong results. It seems that the hotine oblique mercator has some 
problems. Parameters in the transformations seems to be fine.

Is the reprojection console in the 2.1.x version? So I would try to check this 
in the latest 2.1.

Stefan
