XBMC crashing when randomly switching to another media type

OK.. here is the issue I'm running into..

it's completely random... but it happens more often than not. When I'm listening to say music, and I get sick of music, and I want to switch to TV shows, if I go into TV shows, it bombs out and XBMC crashes.

It happens for all of them, if I'm say watching a movie and want to go to music.. or PVR.. it happens more often than not where it bombs out..

any ideas? debug log attached
