Add Printer - Searching for drivers dialog box stays forever.

[Gurvinder Dadyala]

Hi there
I am using Ubuntu Gnome trusty. Issue I am facing is that when adding printer 'Searching for drivers' dialog remains open forever.

How to replicate
- Go to System Settings
- Click Printers icon to add printers.
- Click plus icon to add network printer.
- Select printer from avaiable in network.
- Dialog box appears with mesage 'Searching for drivers'.
- It takes around 5 mins and printer is added however searching for drivers dialog remains open and does not gets closed.
- You will have to 'Force Quit' dialog box.

Searching for drivers dialog remain open forever.

Hi Gurvinder,

I can confirm that this is happening. I just added a network printer and it does take a while. The Searching dialogue box window should close when the device status has changed to Ready.

Additionally, the following doesn't work when trying to close the window:
- Clicking Cancel with the mouse does nothing, no visual feedback
- Focusing on the window and pressing spacebar does nothing even though the 'Cancel' button is already focused.
- Right-clicking on the Searching window and selecting close wants the user to force quit

I can only assume at this point, that the window is stuck in a loop.

[Workaround]
- Once the device status has changed to ready, click on the Printers window and close it.
- The searching dialogue box will still be there, but you can close it with a force quit (right-click window and use close)
- Open printers to ensure previous printer was added.
- [optional] In my case I had to change the model from "Generic text-only printer" to the proper printer driver.

Scp-dbus-service.py seems to be the cause of this behaviour.

This issue has sat incomplete for more than three years now without any response to comment #6 so I'm going to close it as "Invalid".

Please feel free to re-open this bug report if this is still an issue when using a currently supported release of Ubuntu.
