When I use the 'init from epsg'-function with epsg:21781, GM displays the wrong datum as default ('ch1903+' instead of 'ch1903'. I also tried to define a custom epsg code within epsg_codes.txt with the correct datum ch1903, but GM change it automatically in ch1903+.
The same problem is, when I want to import a Geotiff with EPSG:21781 in metadata. Then GM interprets the worng datum too.
Very strange is following behavior: After importing a geotiff with epsg:21781 and saving the GM-Workspace (where the wrong datum CH1903+ is displayed in the bottom right corner), the correct datum ch1903 is dispayed when reopening the workspace. But if I want to export the displayed raster image into a geotiff, GM writes the wrong epsg-code 30600 (local cs) in the metadata of the Geotiff-File.

There is a sample geotiff file with epsg 21781 on my dropbox: https://dl.dropboxusercontent.com/u/33938340/Ortho5cm_21781.tif
