If you click on "recent diary entries" or "recent message entries" from the home page, you get an empty page that contains only the title, but no references to any diaries or messages.
This is more serious than it first appears to be, since this apparently also effects diary entries on the user's page -- you just can't see them anywhere. Which is a pity, since two of my diary entries have effectively disappeared into the void.

fixed, had to create <log:add/> to match <log:recent/>
