            Bug ID: 318844
           Summary: Crash after close System Settings - Printers
    Classification: Unclassified
           Product: systemsettings
           Version: 1.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: jskalaj at gmail.com

Application: systemsettings (1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

Close System Settings - Printers window.
Before it I clicked on the network printer and set it as a default device.
The checking printer as a default device also doesn't work. When I click on the
another printer and back then the check box is not checked.
Moreover no network printer apear in the printing dialog box of Kate, Kile,
Rekonq, etc. . The network printers apear in the dialog box of Firefox and
acroread (but only one).

The printers are given by cups via client.conf file:
ServerName cups.xxx.xxx.xx:1221/version=1.1

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
