            Bug ID: 748175
           Summary: gst_rtsp_server_client_filter hangs
    Classification: Platform
           Product: GStreamer
           Version: 1.4.5
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-rtsp-server
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: james at stev.org
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When calling gst_rtsp_server_client_filter with a function which always returns
GST_RTSP_FILTER_REMOVE and clients are connected to the rtsp will cause random
hangs in the application and the function gst_rtsp_server_client_filter will
never return.

Example code:

static GstRTSPFilterResult KickAllFilter (GstRTSPServer *server, GstRTSPClient
*client, gpointer user_data)
{
        return GST_RTSP_FILTER_REMOVE;
}

GList *lst = gst_rtsp_server_client_filter(m_server, KickAllFilter, NULL);
g_list_free(lst);
