Package: mailcap Version: 3.70+nmu1 Followup-For: Bug #935426 This is still the case in bookworm.
To make 'zathura' the default PDF viewer, I have to use the line | org.pwmt.zathura-pdf-poppler:application/pdf in </etc/mailcap.order>. This one: | zathura:application/pdf does nothing and triggers the above-mentioned warning. -- System Information: Debian Release: 12.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-16-amd64 (SMP w/12 CPU threads; PREEMPT) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages mailcap depends on: ii media-types 10.0.0 ii perl 5.36.0-7+deb12u1 Versions of packages mailcap recommends: ii bzip2 1.0.8-5+b1 ii file 1:5.44-3 ii xz-utils 5.4.1-0.2 mailcap suggests no packages. -- Configuration Files: /etc/mailcap.order changed: org.pwmt.zathura-pdf-poppler:application/pdf -- no debconf information
