I have an odd issue with file associations, trying to open anything with a mime type of application/javascript (.js, .mjs, .jsm) or application/ecmascript (.es) fails with an error "Unknown error code 100 execvp: Exec format error":


Other mime types seem to work. I managed to track this down to my user profile (a new user profile works fine) and kioclient5. kioclient5 exec /tmp/test.js fails, while kde-open5 and xdg-open both work without issues. I've tried everything from here https://unix.stackexchange.com/question ... ssociation , update-mime-database, deleted .cache, all without success. Any ideas what the problem could be or how to debug this?
