Description of problem:

When creating a queue and then sharing it, restricting it to specific
IP addresses the generatet config contains "Listen 10.0.0.2:631"
instead of Allow from 10.0.0.2. The host in question's ip-address is
10.0.0.4.

Version-Release number of selected component (if applicable):

redhat-config-printer-gui-0.6.79.2-1
redhat-config-printer-0.6.79.2-1

How reproducible:


Steps to Reproduce:
1. be root
2. printconf
3. select a queue
4. select menu: action -> sharing...
5. In dialog tab Queue click for "This queue is available to other
computers"
6. Remove the "All hosts" line from the Allowed hosts
7. Add/Single IP address/10.0.0.2 (the address should not be one of
the addresses of your computer) and click ok.
8. click ok in the "Sharing properties" dialog
9. click apply in the printer configuration main window

This is highly bogus and when I add 
  
Actual results:

Inspect the cupsd.conf file genrated and at the very end find "Listen
10.0.0.2:631".

When cups is then _restarted_ instead of just reconfigured it bails
out with this in the messages file:

Jan  3 16:16:10 roke cupsd: cupsd: Child exited with status 99!

Expected results:

Only the Allow from lines generated earlier in the file.  And perhaps
a "Port" command for listening to the network in general, or some
Listen commands for each local address of the computer.
