Hi, as I ran into the same problem, I first searched for the rar-mimetype in systemsettings.
rar is known there as application/vnd.rar but in plugins/clirarplugin/kerfuffle_clirar.json everything refers to application/x-rar After adjusting this setting and recompiling, everything worked like always. I just don't know, if the mimetypes or ark uses an older setting for this. -- MfG. usw. Werner Mahr
