            Bug ID: 309121
          Severity: crash
           Version: 1.0
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: System settungs keep on crashing, when installing a
                    network-printer
    Classification: Unclassified
                OS: Linux
          Reporter: axel.krebs at t-online.de
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: systemsettings (1.0)
KDE Platform Version: 4.9.2 (Compiled from sources)
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Ubuntu 12.10

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

- attempting to install an usb-network printer, I get repeatadly crashes;  
- printer is quite modern Brother HL-2250DN; 
- installing via cups as recommended from BROTHER does _not_ work.
- astonishing (for me): the system settings windows stays open, wheras printer
installing windows crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
