           Summary: QtQuick app crash in dynamic qml object(VideoItem)
                    creation
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: qt-gstreamer
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: joey.chen at balintimes.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


The qml example in qt-gstreamer works well in my Ubuntu desktop and ARM OMAP4.

But crash happened in my QtQuick app:

1. I use "mediaVideo = Qt.createComponent("./VideoItem.qml")" to create an
VideoItem object in qml, that qml file contains almost the same code as
example;

2. Once the video finish playing, the VideoItem will automatically destroy
itself, using: "videoItem.destroy()"

3. If another video file ia available in my playlist, then repeat step 1
crash at here, gdb report that "segmentation fault", from libQtQuick.so


PS: qt-gstreamer source code from git in Feb-23, 2014
