When you make a post without a Tite in P2 with a < or > in the text P2 then creates a post without a title. The posts seam to hang P2 theme but if you make a browser refresh there will be a empty post. This post is a little tricky to delete. you´ve got to change category in admin to be able to "move to trash". ist not unlikely that users use the > character in posts. We need a fix please.
