    yes, a screenshot would help. If this is a Python error message then I could look at it. If this is an Inkscape crash, then I would recommend reporting is as a separate, new, bug, because the same problem will also be encountered by other export programs, not just the dxf program.
    Also, if you are getting an actual crash in Windows, then you can often trap useful exit messages by running Inkscape from a DOS prompt and using the methods outlined in http://kaioa.com/node/63
