Verify Disk is full of odd messages - should I be worried?

My Mac froze recently. Force Quit didn’t help so I restarted it and ran Disk Utility as a precaution. Verify disk usually just shows half a dozen lines followed by the reassuring message: Your disk appears to be OK. But now I’m getting a ton of stuff. I’m used to getting a load of ‘SUID’ warnings that I can ignore with Repair Disk Permissions - but not with Verify Disk. still get an OK message - but it doesn’t come at the end.

Is this something new in Mavericks. Should I be worried?

Here is the message I’ve received.I’ve run Verify Disk 3 times now but I still get all this:
