SOLR 1.2 - Duplicate Documents??

Hey all, I have a fairly odd case of duplicate documents in
our solr index
(See attached xml sample). THe index is roughtly 35k in
documents. The only
way I've found to fix the problem is to run a delete
statement by id, which
deletes both, I can then re-index that one document. This
happened
previosuly but it ended up being an issue with
case-sensitivity but this
time the id's appear identical! 

Any assistance in tracking this down would be appeciated! I
can provide any
other logs if nesseary.

Thanks,

Dan

Have you edited schema.xml since building a full index from
scratch?  If 
so, try rebuilding the index.

People often get the behavior you describe if the 'id' is a
'text' field.
