Description of problem:
In Fedora 14 I had two network printers configured which are no longer accessible from Fedora 15. When trying to print to one of them, a notification comes up saying that the printer may not be connected. 
In the CUPS management web interface, the status of the printers is 'Paused - "/usr/lib/cups/backend/dnssd failed"'

Version-Release number of selected component (if applicable):
1.3.2

How reproducible:
Always

Steps to Reproduce:
1. Configure network printer in Fedora 14
2. Upgrade to current Fedora 15 beta
3. Try to use printer in Fedora 15
  
Actual results:
Printing documents fails

Expected results:
Printing works as it did before

Additional info:
I also was unable to add the printer again, as s-c-p didn't find any network printers at all (repeatable between system restarts). I decided to restart the avahi daemon via system-config-services and after that, the network printers suddenly appeared in s-c-p (and worked!) but the old printer definition was still disabled.
