Thanks. We are working through these haphazardly.

The aim is to present known errors clearly and succinctly but not hide the
traceback when a genuinely unexpected thing happens. We never want the
short message to lie. It gets harder as we progress.

If you open bugs on https://bugzilla.samba.org we will not loose track.

The attached patch is probably right for this one.
