Just because the backtrace points to it doesn't mean mean it is a fault from the video driver, it could happen that WINE is sending wrong instructions. Just saying that it could have beeen premature to dismiss this as invalid.
Just for the record, this is true in the general case. GL context management bugs will typically create a backtrace that points to the video driver.
