Bug#729713: libcups2: fails to fetch ppd of ipp:// device

[Wolfgang Walter <wolfgang.walter@stwm.de>]

We see the same problem here:

we have a cups printer server say cups.localdomain.tld with a lot ipp-
postscript-printers. The clients are configured to use the cups-server. Since 
1.6 the client tries to get the ppd from the printer instead from the server.

A workaround is use a device-uri starting with http:// instead of ipp://

ipp://bla.localdomain.tld:631/ipp

=>

http://bla.localdomain.tld:631/ipp 


We modified libcups in the same way as Lionel. I don't know why this has been 
changed from 1.5 to 1.6 but it seems buggy. Most ipp-printers don't provide a 
PPD. And even if the do there is no guarantie the client is allowed to 
communicate directly with the printer.
