Title:
  ImageMagick convert SVG core dump

Status in imagemagick package in Ubuntu:
  Confirmed

Bug description:
  I am experiencing the following bizarre crash when attempting to
  convert SVG images:

  # download a sample image
  wget https://upload.wikimedia.org/wikipedia/commons/6/67/Firefox_Logo%2C_2017.svg
  # re-download the same image with a different name
  wget https://upload.wikimedia.org/wikipedia/commons/6/67/Firefox_Logo%2C_2017.svg -O firefox.svg
  # even copy the original image to a different name
  cp Firefox_Logo,_2017.svg firefox2.svg

  # no convert the images (recall they are identical)
  convert Firefox_Logo,_2017.svg firefox.png  # works
  convert firefox.svg firefox.png             # Aborted (core dumped)
  convert firefox2.svg firefox.png            # Aborted (core dumped)

  The problem can be reproduced at least on two different laptops
  configured similarly (but based on different hardware), so it is not
  random and not specific to one system.

  The system specs are as follows:

  me at ubuntu:~$ cat /etc/lsb-release 
  DISTRIB_ID=Ubuntu

  DISTRIB_CODENAME=xenial
  DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS"

  me at ubuntu:~$ convert -version # installed from repo

  I could solve the problem by installing ImageMagick from source as described here
