It's certainly worth upgrading.  Several bugs in the Quartz backend were 
fixed, a couple of which could have caused this problem:

* Fixed bug which meant we sometimes failed to remove a posting when
   deleting or replacing a document.

* Fixed PostlistChunkReader to take a copy of the postlist data being
   read to avoid problems with reading data from a string that's been
   deleted.

* Fixed bug in postlist merging which could occasionally extend a
   postlist chunk to overlap the docid range of the next chunk.

Hopefully 0.8.1 will fix the problem - let us know if not.
