Package: mime-support
Version: 3.51-1
Severity: wishlist
When the user runs a text program that uses the mailcap system (e.g.
Mutt) in GNU Screen, it is not possible to run as X11 program via the
mailcap system after the X11 session has changed, because the value
of $XAUTHORITY has changed. Using a fixed symlink (in a private
directory, for more security) to the real X authority file, possibly
depending only on the screen session, and updated via a screen
wrapper, might work as a work around, but has some limitations
(e.g. because several screens could be used on several displays)
compared to the following suggestion.
It should be possible that the program specified in the mailcap
configuration be run by a user-provided shell, typically using
the $SHELL environment variable, without modifying the mailcap
configuration (because this configuration may already be provided
by the system, here Debian). For instance, with zsh, the .zshenv
file is always sourced and could do the necessary to fix the
environment.
Though this is up to the various programs to do that, the mailcap
specification should allow them to do that.
The mailcap(5) man page currently says:
The "command" field is any UNIX command ("cat %s" in the above
example), and is used to specify the interpreter for the given
type of message. It will be passed to the shell via the system(3)
facility.
but system(3) specifies that /bin/sh -c is used to run the command.
The mailcap(5) man page should say:
It will be executed either with the user's shell or with the
system(3) facility.
