            Bug ID: 334013
           Summary: systemsetting crashes when selecting "printers"
    Classification: Unclassified
           Product: systemsettings
           Version: 4.11.8
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: f.presel at alice.it

Application: systemsettings (4.11.8)
KDE Platform Version: 4.12.4
Qt Version: 4.8.6
Operating System: Linux 3.13.5-laptop x86_64
Distribution: SolydXK

-- Information about the crash:
- What I was doing when the application crashed:
I opened systemsettings; from the first screen there I selected (double-clicked
on) the printer configuration icon (print-manager).
Systemsettings immediately crashed; on the terminal, I only see:
KCrash: Application 'systemsettings' crashing...

This occurs since I installed a new printer using system-config-printer (i.e.
the GTK frontend)

The crash can be reproduced every time.

-- Backtrace:
Application: Impostazioni di sistema (systemsettings), signal: Segmentation
fault
