           Summary: attempting to play a zero-length file causes SEGV
           Product: juk
           Version: 2.0.1
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: wheeler kde org
        ReportedBy: jm-kde jmason org


Version:           2.0.1 (using KDE KDE 3.3.0)
Installed from:    Debian testing/unstable Packages
OS:                Linux

What the title says -- if a file exists with the right extension (".mp3") under a JuK-watch directory, and you double-click it in the track listbox, JuK dumps core.

To reproduce:

    - touch [MYCOLLECTIONDIR]/EMPTY_TEST.mp3
    - juk &
    - select Collection List
    - [wait for juk to find the file]
    - click on "EMPTY_TEST"
    - KDE crash window appears.

I'm using GStreamer btw.

I'm not sure how feasible it is to capture GStreamer coredumps, but it'd be nice -- since it does seem to have a tendency to fall over frequently ;)

probably not-too-useful backtrace:
