multiple nodes from "one of" filter argument

Hey, I'm using views to select nodes from "one of" two categories (tids). What's happening is that if a node is in both categories, the view is displaying the node twice.

Looking at the sql query, if I add "distinct" to the node select query (through the mysql shell), I get the correct, each node once result. Unfortunately if I add "distinct" to the views_query.inc it doesn't seem to change the result in drupal. Another method might be to cull the doubles from the nid list that is returned.

Anyone else experience this bug? Any ideas on where to fix it properly?
