Yes, it's clear to me what happened.

I'm afraid so... :-(

Previously we would explicitly check if sptr was a NULL pointer. This  
was missed in commit r1429, so depending on what the state tree looks  
like at the moment of calling dstate_delinfo(), we risk referencing a  
NULL pointer. Oops.

This should be fixed in r1666.
