[Bug 883359] [NEW] imagmagick convert leaves files in /tmp after exiting with error

[Brian St. Pierre]

Public bug reported:

The following SVG file (also attached) has a NUL character just before
the "/" in the <path /> element.

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg">
  <path  />
</svg>

This is invalid XML. convert dies with an error message:

% convert fail_166.svg fail_166.png
convert: Couldn't find end of Start Tag path
 `` @ svg.c/SVGError/2550.
convert: missing an image filename `fail_166.png' @ convert.c/ConvertImageCommand/2838.

It exits with error code 1 -- not an uncontrolled exit like a segfault.
It leaves behind a file in /tmp/ -- this is the bug. It should clean up
the tmp file before exiting.

% cat /tmp/magick-XXi9qeeM
push graphic-context
encoding "UTF-8"
viewbox 0 0 0 0
affine -nan 0 0 -nan 0.0 0.0
push graphic-context

Running bulk conversions on many invalid SVG files results in many files
left behind in /tmp.
