Heads-up: dopus_fileinfo crashes and solution

Update: A workaround for this problem is included in Opus 9.1.1.8. See above.

Please see Heads-up: dopus_fileinfo crashes and solution if you're using the new CSV/RTF/Font/Postscript plugins and have found Opus crashes sometimes.

Hopefully the plugins will be easy to fix but I figure the mysterious crash may be causing problems for some people so it's worth giving everyone a heads-up on how to avoid it for now.
