Wow, what kind of ***** is this? Never seen before. Sorry dude, I have no idea. Maybe you should do all the normal repair stuff people normally do when having weird problems. Repair Lion, re-install Apps and so on.
You might try turning off time machine backups if they're on. I had an error that looked pretty much like that, and that stopped it for me. Unfortunately that doesn't actually fix what's wrong, just stopped the symptom.
