If you create two discussions with the same title, it will let you create them, and will display both in the sidebar, but you can only get to the first one. I think this is because the permalink is the same. Maybe we should change generate_permalink to check if it's unique?
I think the issue is using permalinks in general. They're convenient and make nice URLs, but I think a permalink + ID system would be much more useful.
