I had a similar problem, with a similar backtrace, using an nvidia card.
I had reported it as well as my (or marcin's) solution here. 
Solution: Don't use the builtin randr stuff. use xrandr itself.
Maybe that helps you, too. The developer of the free nv driver said, it's
likely a bug in X.org / randr but of course I thought NetBSD was the culprit.
