gs 9.07 can't render ps files on comma-locales [fixed]

Okular and other libspectre based PostScript viewers can't render some ps files when using a locale that uses , instead of . for decimals.

This happens because of a bug in ghostscript 9.07 that has now been fixed.

I'm not a huge fan of distro-patches myself, but in this case it may make sense to have one, so feel free to ping your distribution if you are a PostScript user.
