Bug#380730: GnomePrintCupsPlugin-Message: The ppd file for the CUPS printer $remoteprinter could not be loaded.

[John R. McPherson]

Package: libgnomecups1.0-1
Version: 0.2.2-1ubuntu5.1

(yes so I'm using ubuntu, but this information might help with this bug
anyway).  I have a debian cups server, and an ubuntu client.

On the client, lpstat -l -a -p gives:
printer PDF_Spooler is idle.  enabled since Tue 24 Oct 2006 18:02:46 CEST
[...]
        Connection: remote
        Interface: ipp://192.168.1.2:631/printers/PDF_Spooler.ppd
printer Stylus_DX3800 is idle.  enabled since Tue 24 Oct 2006 18:02:46 CEST
[...]
        Connection: remote
        Interface: ipp://192.168.1.2:631/printers/Stylus_DX3800.ppd

When the gnome print dialog comes up, stderr on the client gets the message
"""
GnomePrintCupsPlugin-Message: The ppd file for the CUPS printer PDF_Spooler could not be loaded.
GnomePrintCupsPlugin-Message: The ppd file for the CUPS printer Stylus_DX3800 could not be loaded.
"""

and I can see in my local client's /var/log/cups/access_log file the
corresponding lines:
localhost - - [24/Oct/2006:18:15:22 +0200] "GET /ppd/PDF_Spooler.ppd HTTP/1.1" 404 0 - -
localhost - - [24/Oct/2006:18:15:22 +0200] "GET /ppd/Stylus_DX3800.ppd HTTP/1.1" 404 0 - -

I don't know whether cups' browse protocol is supposed to send the
ppd files from the server to my client, or if the client is supposed to
be requesting those ppds from the server instead of localhost.

The version of cups on the client is 1.2.2 (ubuntu), and on the server
it's 1.2.1 (from backports.org for sarge).
Based on googling, this doesn't seem a particularly widespread problem,
so maybe it's something to do with the differing versions?
