2.2.0 rc2-1 when I try to open dxf created by other programs (Autocad, Artcam, CuttingPro) LibreCad opens file then fires a message that file not exist or to check premisiions and then closes the file. With 2.2.0 rc2 and preious versions opening such file is not a problem. OS Windows7. Attachment is one of files I can't open.
Many thanks for reporting this.
Basically it was a missing newline at the end of the file, but this brought up some other issues which should be fixed now too.
Fix with commit 369783f
