[Zope] ERROR Zope.ZCatalog reindexIndex could not resolve an object from the uid

[Manuel Vazquez Acosta]

Hi all,

I'm facing some trouble with a Plone Site. When trying to insert a new 
page I get an error complaining about some lost uid.

I have tryied clearing uid_catalog's indexes: UID, id, and Title. Then I 
reindex those indexes, and in the event.log I got several errors:

ERROR Zope.ZCatalog reindexIndex could not resolve an object from the 
uid '/path/to/the/object'

Does anyone knows how to troubleshoot this?

Thanks in advance,
Manuel.
