handle_*_request() functions were all retrieving the session media from the session by calling gst_rtsp_session_get_media () which is a transfer-none call. If a session timeout happens at that time, the session media may get freed making the pointer invalid.. Fixes #757 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1053>
