[Zope] ZCTextIndex - Collector Item #505?

[Jonathan]

I have encountered an unusual situation which I believe may be related to 
collector item #505  (http://www.zope.org/Collectors/Zope/505 - ZCTextUndex 
should not hold a reference to a lexicon).

Prior to performing a ZCatalog update I cleared the catalog (using the clear 
catalog option under the Advanced tab of the ZMI); then, to clear out the 
Lexicon, I deleted the Lexicon and created a new Lexicon (id of both was 
'Lexicon').

I then added about 805,000 records to the ZCatalog (which went smoothly) and 
tested catalog searches - all went well, including globbing searches, 'and', 
'and not' searches.

The previous Lexicon had 764,410 word entries.  The current Lexicon has 0 
word entries.

The ZCatalog and ZCTextIndex appear to be working ok, so I am guessing that 
somehow the ZCTextIndex is using a 'hidden/old' version of the Lexicon (not 
the newly created version) - which is very strange, as the .fs file was 
packed prior to the update (so any old versions should have been deleted).

This activity was all performed on a linux server running zope 2.6.1

Finally, the questions:

1) Can ZCTextIndex really be using the some other version of the Lexicon 
(which I can not access via the ZMI)?
2) Was Collector Item #505 ever fixed (I can not find a reference to issue 
#505 in any of the zope change logs)?

Thanks,

Jonathan
