Hi' I replaced the dxf_input.py by the one in the link you sent. I tried again to open the same file that caused the same error BUT the file was stored on an USB key so I copied it on the desktop to ensure that the bug couldn't come from the "location" or "device" and surprisingly inkscape was able to open it. As I launched Inkscape from a terminal here's what it "says" : ** (inkscape:7017): WARNING **: Malformed URI I can't say now that I replaced the dxf_input.py file if it is because of the new one that it work or if the trick is that it doesn't want to load from a USB key... I'll send you the dfx file I was trying to work with. Perhaps it should help to determine the problem. Thx for being so reactive and for this great program !!!
