FS#1088 search with "not" word but no "and" hits gives php warning

Doing a search with $conf['text_indexer']=1 and a "not" word but no "and" hits, such as "?do=search&id=-nonword" or "?do=search&id=nonhit+-nonword" gives php warnings:

Warning: array_keys() [function.array-keys]: The first argument should be an array in /inc/fulltext.php on line 43
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /inc/fulltext.php on line 43

I see this ONLY as a result of using $conf['text_indexer']=1 so perhaps idx_lookup() is not returning an array???

Thanks, Y'all
