It's apparently a kernel bug. (You won't see that message if it's a
NULL pointer in user-space code like NUT - it'll say something like
"Segmentation fault" in your terminal, not in the syslog.)

Unfortunately, you probably won't have much luck getting the Linux USB
stack maintainers to look at this because of the closed-source nvidia
module that is loaded.

Do you see any kernel messages right before the NUT "check driver" messages?
