[Pkg-cups-devel] Bug#372586: cupsys: passes wrong command line arguments to backend

[Julien BLACHE]

Package: cupsys
Version: 1.2.1-2
Severity: grave
Justification: renders package unusable

Hi,

Either CUPS 1.2 passes wrong command line arguments to the backends, or the
parallel backend bundled with CUPS 1.2 is buggy in some way.

Either way, I am unable to print using the parallel backend; the backend
returns a failure code.

Trying to print a test page, here's what happens:

--- backend environment:
declare -x CHARSET="utf-8"
declare -x CONTENT_TYPE="application/postscript"
declare -x CUPS_CACHEDIR="/var/cache/cups"
declare -x CUPS_DATADIR="/usr/share/cups"

Executing the parallel backend:
% ./parallel --help
Usage: parallel job-id user title copies options [file]


If this is not Debian-specific, then I really wonder how much QA is done on
CUPS releases upstream...

I tried recreating a printer from scratch, same result.

The parallel backend works OK when run by hand with the right command line
arguments (surprisingly, sigh.).
