Ao tentar adicionar uma impressora, o sistema retorna uma mensagem de erro. Além do mais, não consegui localizar uma impressora em rede.

I went to add a Kyocera Mita FS-1030D+ with an IB-21E NIC.

1. Tapped Windows key
2. Searched for "printers"
3. Saw list of printers already added in settings app in printer section
(Two printers originally listed - one not connected, one auto-added by network detection)
4. Clicked "Add" button in the titlebar to add Kyocera
5. Add printer dialog appears, spinner shown briefly, then "System program problem detected"

I now get a similar system program problem detected every time I sign into my account.

I was able to add the printer through older looking Gnome printer dialog ("Additional Printer Settings" button), but still get a crash every time I sign in.

[ADFH (adfh)]

I've gotten around the bug by:
* Shutting down cups service
* Deleting
  * /etc/cups/printers.conf*
  * /etc/cups/classes.conf*
  * /etc/cups/subscriptions.conf*
* Rebooting
* Adding printer using the "Additional Printer Settings" button rather than the "Add" button on initial screen

All three sets of deleted files were auto-created again, and no crash dialog appeared.
