Package: mime-support
Version: 3.62
Severity: important
According to the mailcap.order(5) man page,
"The order of entries in the /etc/mailcap file can be altered by editing
the /etc/mailcap.order file. Each line of that file specifies a package
and an optional mime type."
This only holds true if the package adds a file to /usr/lib/mime/packages.
Many /etc/mailcap entries, however, are obtained by parsing files in
/usr/share/applications; in that case the "package" name is taken to be
the name of the .desktop file, minus the .desktop suffix. In some cases
this is different from the actual package name. Moreover, the name can
change in a package's history, resulting in surprising behaviour changes
across release upgrades if /etc/mailcap.order isn't updated to match.
The behaviour is old but became noticeable for me after upgrading from
stretch to buster. evince.desktop was renamed to org.gnome.Evince.desktop,
causing gimp to become the preferred PDF viewer. As I tried to correct
this by adding
evince:application/pdf
to the mailcap.order file I got a warning
"Warning: package evince listed in /etc/mailcap.order does not have mailcap
entries."
and no reordering of entries.
