            Bug ID: 323952
           Summary: KsCD crashes when I try to play a CD
    Classification: Unclassified
           Product: kscd
           Version: 1.5
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kde-multimedia at kde.org
          Reporter: jetrull at sbcglobal.net

Application: kscd (1.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
attempting to play a CD.  Title of CD is displayed, but it does not play (just
sort of sits there, showing no progress on the track).  I have pressed the play
button, if that's not obvious.  Eventually it crashed - I may have hit play a
couple of more times, or tried a different CD, I can't recall.  Hopefully the
stack trace will provide some insight.

-- Backtrace:
Application: KsCD (kscd), signal: Aborted
