xine-ui works fine, as does the audio test and video test in the gstreamer-properties. It occurs only in the X11/XShm/Xv output sink with totem. (To be expected, given the strace and gdb...) Just so we're clear, it's _most_ movie files, not all of them. -- Totem crashes on startup. https://launchpad.net/malone/bugs/39050
