Yes, it can.  The ZCTextIndex holds an attribute, 'index', which is an
instance of either OkapiIndex or CosineIndex.  That subobject also holds
a reference to the lexicon, which is the reason for the collector follow-up:

 Partial fix in place. I still need to resolve the deeper reference held
 in the actual index object that ZCTextIndex delegates to (more fun and

No, it has not been fixed.  The workaround in your case is to delete the
entire ZCTextIndex, re-add it, and re-index your content.  You might be
able to revivify the current lexicon by opening the database yourself,
but the risk / reward ratio is pretty steep, compared to just recreating
the index.
