Hi Kevin J. McCarthy, oh this is embarrasing! You're right of course.
> > PS: I'm using the Ubuntu package: 1.13.2-1ubuntu0.4 Yes, but I also installed mutt 2.0 manually to /usr/local last fall because there was no deb package yet. Apparently the file mime.types wasn't installed to /usr/local/etc/mime.types for an unknown reason. I fixed my problem like this for now: ln -s /etc/mime.types /usr/local/etc/mime.types But will switch to the buster-backports package soon. So sorry for the unnecessary noise!
