Division by Zero

[Miles B Huff]

When attempting to save the attached file as an Optimized SVG, I get the following error (on both Inkscape 0.92 and 0.91):

Traceback (most recent call last):
  File "scour.inkscape.py", line 73, in <module>

ZeroDivisionError: float division by zero

reproduced on Windows 10, Inkscape 0.92.2 (5c3e80d, 2017-08-06)

probably related to the fact that the viewbox has zero width in the document.
The viewbox is given as:
   viewBox="-3240000 0 0 1100"
 I would suggest manually editing the viewbox attribute to give it a size consistent with the page dimensions

Alvin,

Thank you; that worked.

Even so -- Inkscape needs to be able to account for SVG files with incorrectly-set viewboxes, and to prevent such situations from arising in the first place (I created this file in Inkscape and have only ever edited it therein.).
