It is crashing in libcdio which has been updated recently.
Could you please try downgrading libcdio13 and trying version from
experimental to rule libcdio out?
If it is still crashing I suspect a memory allocation handling
problem. Could you please test the bug using valgrind?

I looked at XBMC's code and it seems to be OK.

Cheers,
