In Zope 2.8 you are recommeneded to run covertIndexes on all
catalogs.  But if you export a catalog from 2.7 and import it
into 2.8 - there is no way to run covertIndexes.  What seems
to bomb is in PluginInxes/common/UnIndex.py where the internal
state of the indexes are referring to _length for BTrees.Length.Length
but the older indexes attribute is __len__.  So we have to try/except AttrError
around this and migrate in-place.  

NOTE: after I imported I still had to run catalog/manage_convertIndexes
