Description of problem:
When connecting an Epson Stylus D78, no queue is added even though gutenprint-cups supports a very close match and is installed.  This worked in Fedora 14.

Version-Release number of selected component (if applicable):
gnome-settings-daemon-2.91.93-1.fc15.x86_64
gutenprint-cups-5.2.6-3.fc15.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Connect printer for which there is no exact driver match
  
Actual results:
1. A notification is displayed briefly

Configuring new printer
Please wait...

2. gnome-packagekit dialog is seen, querying available drivers.  This does not find any (expected)

3. The 'Configuring new printer' notification is replaced by another notification:

Missing printer driver
No printer driver for EPSON Stylus D78

This disappears after a very short time.

Expected results:
Either the queue should be configured using a close-matching driver, for example the one used in Fedora 14 was "Epson Stylus D68 - CUPS+Gutenprint v5.2.6 Simplified",

OR, the user should be given some indication as to what they are supposed to do next to get their printer working.
