Error: failed to create SVG output file 'save_to_png.svg'

[richelbilderbeek]

From #250 :

Segmentation fault (core dumped)
convert_dot_to_svg: warning: command 'dot -Tsvg save_to_png.dot -o save_to_png.svg' resulting in error 35584
convert_dot_to_svg: failed to create SVG output file 'save_to_png.svg'
ICE default IO error handler doing an exit(), pid = 18628, errno = 32

Possible causes:

• likely: dot/graphviz is not installed: module load graphviz
• likely: you've run a release version, where the debug version would give you helpful information
• less likely: something with the .dot file: post it here

To solve this bug:

• mention the environment it occurs (Peregrine, LWP, local, Travis CI)
• mention if you've used a debug or release version
• post the .dot file

Moved to #264
