This isn't a Docker image matter. It's either an upstream server matter or an app that registers mime stuff inappropriately.

However, can you provide the output of the following (from inside your app container)?

diff /usr/src/nextcloud/core/js/mimetypelist.js /var/www/html/core/js/mimetypelist.js

That will likely provide a clue was to what app is triggering this [which also might help others searching here].

You can also manually overwrite your environment's mimetypelist.js with the distributed one with the following command (inside the app container - or equivalent):

cp -av /usr/src/nextcloud/core/js/mimetypelist.js /var/www/core/js/

Then trigger an integrity recheck.

The upgrade to 28.0.1 fixed the issue, since I can't reproduce it anymore I'll go ahead and close this issue now. Thank you for your help!
