Yeah but this all assumes a hierarchical data model.  What about changing
an item's name?  In dav, that means moving, but what about in other

I agree with what you suggested.  We should catch the exception, log it, and
return a 500 minus the nasty stack trace.  Then we can see how often this
happens and figure out a solution.
