[O] Bug: Preview equation fails using dvipng - incorrect string [9.0.1 (9.0.1-elpaplus @ d:/Users/nish.joseph/.emacs.d/elpa/org-plus-contrib-20161118/)]

[Nish Joseph]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

The process to create PNG of equation fails as there is an added `"` in
the command line string. Expected behaviour is the correct command 
line args to generate a PNG. dvipng works fine on a separate terminal. 
Here is the partial list from my limited knowledge of debugging

shell-command("dvipng -fg \"rgb 0.972549 0.972549 0.94902\" -bg \"rgb
0.156863 0.164706 0.211765\" -D \"120.0\" -T tight -o
\"d:/Users/nish.joseph/AppData/Local/Temp/\"\"orgtex7708Klj\".png
\"d:/Users/nish.joseph/AppData/Local/Temp/orgtex7708Klj.dvi\"" #<buffer
*Org Preview LaTeX Output*>)

The problem i suspect is
\"d:/Users/nish.joseph/AppData/Local/Temp/\"\"orgtex7708Klj\".png

Kind Regards
