I have seen this several times:

  For some problems during product import, Zope
  decides to keep the old state rather than show
  the error.

This is *very* confusing.

If you have a sufficiently recent Zope version
(I think, at least Zope 2.2.2), then enabling
the "stupid logging mechanism" should give
you an error indication in the log file.

You activate this logging through a parameter:

    STUPID_LOG_FILE=zope.log

for your start script.
