           Summary: Kdenlive crash when overwriting existing file
           Product: PulseAudio
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core
        AssignedTo: pulseaudio-bugs at lists.freedesktop.org
        ReportedBy: admin at temperage.com

Application: knotify4 (4.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.35.13-92.fc14.i686 i686
Distribution: "Fedora release 14 (Laughlin)"

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

1. Open Kdenlive and add a new clip to the project tree and then to the
timeline
2. Click render button
3. Choose any existing *avi file on the system as the output target
4. Click "Render File"
5. The "Warning Kdenlive" popup will appear. As soon as you move the mouse over
the popup, the app crashes.

Everything works as expected if you give a unique name to the output file.
Crash happens only when attempting to overwrite existing file. It does not have
to be the clip source file.

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
