Bug 392078

Application: systemsettings (4.11.22)
KDE Platform Version: 4.14.30 (Compiled from sources)
Qt Version: 4.8.7
Operating System: FreeBSD 10.4-STABLE amd64
Distribution (Platform): FreeBSD Ports

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to troubleshoot a disk mounting error. Attempted to open the "Removable Disks" group in System Settings. I never even got the window to open because the crash interrupted it.

- Unusual behavior I noticed:
I am having trouble mounting a CD. Opening Dolphin and selecting "CD" gives the error: "An error occurred while accessing "CD", the system responded: org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freedesktop.hal.storage.mount-removable no <-- (action, result)"

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Abort trap
