Bug#367198: /etc/bash_completion: [COMPLETION] when completing for package, there are often warnings that get in the way

[Remi Vanicat]

Package: bash
Version: 3.1-4
Severity: minor
File: /etc/bash_completion
Tags: patch

When completing for a package, often I've somethin like:
$ reportbug ocW: Impossible de localiser la liste des paquets sources 
ftp://ftp.uk.debian.org sid/main Packages 
(/var/lib/apt/lists/ftp.uk.debian.org_debian_dists_sid_main_binary-i386_Packages)
 - stat (2 Aucun fichier ou répertoire de ce type)
W: Impossible de localiser la liste des paquets sources ftp://ftp.uk.debian.org 
sid/contrib Packages 
(/var/lib/apt/lists/ftp.uk.debian.org_debian_dists_sid_contrib_binary-i386_Packages)
 - stat (2 Aucun fichier ou répertoire de ce type)
W: Impossible de localiser la liste des paquets sources ftp://ftp.uk.debian.org 
sid/non-free Packages 
(/var/lib/apt/lists/ftp.uk.debian.org_debian_dists_sid_non-free_binary-i386_Packages)
 - stat (2 Aucun fichier ou répertoire de ce type)

And it it then difficult to know what happen. 

It come from call to apt-cache when stderr is not redirected to /dev/null.

I attach a patch that resolve the case I've seen in /etc/bash_completion.
