A little more investigation and items is not being called between each song. My guess is that the real problem is elsewhere and this is just a symptom of a core problem. May be a thread this has not been exited or a lock that is not being released. AFAIK it is rc.py that controls the detached audio so this is the next place to check. There is a problem with slide shows that contain audio and the audio finishes before the slides, this causes a crash in freevo.
