            Bug ID: 329121
           Summary: KsCD crashes when skip is pressed before play
    Classification: Unclassified
           Product: kscd
           Version: 1.5
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kde-multimedia at kde.org
          Reporter: ejones34 at sycamores.indstate.edu

Application: kscd (1.5)
KDE Platform Version: 4.12.0
Qt Version: 4.8.5
Operating System: Linux 3.12.6-1-ARCH x86_64
Distribution: "Arch Linux"

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

I opened KsCD from the Available Devices menu (as an option for an inserted
optical disk) in the notification bar and clicked the skip right button before
interacting with any other part of the application.  The application crashes
right as I click skip right.

The crash can be reproduced every time.

-- Backtrace:
Application: KsCD (kscd), signal: Segmentation fault
