[Bug 1279069] [NEW] Systemsetting crashed when using Driver Manager for Kubuntu

Tue Feb 11 20:41:01 UTC 2014

Public bug reported:

I first reported the crash (bug) via drkonqi, my fault. But here what
happened and the Backtrace. Hope it helps!

Application: systemsettings (4.12.2)
KDE Platform Version: 4.12.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-8-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I've installed the kubuntu-driver-manager package. After installation I started Systemsettings >Driver Manager for Kubuntu. It worked well until I clicked on "refresh driver list" because Systemsetting crashed immediately

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
