Bug 318844

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
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
