OpenSCAD version 2019.01-RC2  Import fails without error when using relative path

 translate([0,0,50]) import ("PRINT3D/FILE.stl");   // this one is displayed
 translate([0,0,-50]) import ("FILE.stl");

I'm trying to import a stl file, which is located at /home/ben/Documents/PRINT3D/FILE.stl, the file NOTFOUND.stl don't exist.



when i start a new file by starting new instance of openscad, then select "new" without saving the file,

i type the following code

 import ("PRINT3D/NOTFOUND1.stl");
 translate([-50,0,50]) import ("Documents/PRINT3D/FILE.stl");  // this one is displayed
 translate([0,0,50]) import ("PRINT3D/FILE.stl");
 import ("PRINT3D/NOTFOUND2.stl");
 translate([0,0,-50]) import ("FILE.stl");
 import ("NOTFOUND3.stl");
