I know. It's a bug -- not in Ethereal, but in the device sending the 
packet. This is one of the reasons why I originally implemented this 
option 43 dissection (to make those bugs visible) and why I didn't make 
the capture publicly available (to not blame on that particular vendor 
-- other's aren't any better).

Yes, I hadn't noticed this yet: those parts of DHCP option 122 
dissection got broken, too. I'm pretty sure this has been working before 
(in Rev. 12338).
