I am not seeing anything obvious on my end.  Is there a specific 
application, or other behavior that you can do to trigger this? Might 
also be worth making sure you aren't having any hardware issues (check 
memory for example).

This section of the developers handbook might also be helpful.  It walks 
you through capturing and then analyzing a coredump:
