yes, I believe you were right on your previous comment. Someone had deleted an 
early priv'd user and left over acl's were causing the problem.  

Perhaps a dependency check when building the acl hash to see if that principal 
id still exists, otherwise skip it?

I'll run another dump and see if I run into any more irks.
