dvipdfm compat bug

[Karl Berry]

    This is probably a bug in dvipdfmx.c around line 1082: my_name is not set.

Thanks Christian. I forwarded to dvipdfmx at tug.org so all the maintainers
there would see it. I hope we can fix it in short order.
    
    By the way, does it make sense to submit pull requests at
    https://github.com/TeX-Live/texlive-source?

Not really, since the real sources are in our svn and few of us do
anything with the github (I don't, for instance :). So I suggest sending
diffs to tlbuild at tug.org, a much smaller list than this one, though here
is also ok. Thanks. -k
