[PyKDE] Problem with Socket Inter-Process Communication preventing HPLIP from faxing

[Till Kamppeter]

Hi,

I have a problem with HPLIP and PyQt (python-qt) 3.16. With the update 
from 3.14 to 3.16 on Ubuntu Edgy the fax functionality (and perhaps also 
other functions) of HPLIP stopped to work. Mandriva 2007 still uses PyQt 
3.14 and there faxing with HPLIP works.

HPLIP uses sockets to let the daemon (hpssd) pass data of a print job 
sent into a fax queue to the fax GUI (hp-sendfax). The fax GUI does not 
receive this data when PyQt 3.16 is used, but it receives and processes 
the data correctly when PyQt 3.14 is used.

HPLIP versions are 1.6.7, 1.6.9, and 1.6.10.

Tested operating systems:

Mandriva 2007 (PyQt 3.14): works
Ubuntu Dapper/6.06 (PyQt 3.14): works
Ubuntu Edgy/6.10 (PyQt 3.16): fails

So there is a regression from Ubuntu Dapper to Edgy, faxing 
functionality for HP's MF devices gets lost.

See also the Ubuntu bug report on this:

As Ubuntu is already in freeze for the final Edgy, it would be great if 
the problem could be fixed by a small patch.

I am grateful for any kind of help.
