Hmm, this is not something we've seen before. Are there other files in the project that are loading from the same location and loading and rendering correctly? If so what file types/node types are they? e.g. Image Map Shader, OBJ node, etc.
One possible explanation is the file is actually loading, but the georeferencing isn't working correctly for some reason. If that were happening, the file would be loading but would probably end up at the 0,0,0 coordinate origin. Something you can try is to switch to Manual Georeferencing. It should maintain the settings from Auto, so the position should remain the same, but it won't rely on auto-gereferencing when it loads as far as I know. i.e. it should fix the problem if that's the issue. If so definitely let us know so we can fix it. Alternatively you could try moving the camera to 0,0,0 without making any other changes and see if the terrain is visible there.
Also, just to make sure, are you running the same exact version on Linux as you are on Windows?
