[STUMP] Crash Report

[iii_iii]

Hi, I have received a crash. I haven't pasted the whole thing as I am 
not sure if it is worth it. I am using an nvidia driver, and I was 
trying to clone the display onto tv-out. There are warnings about the 
nvidia driver when I start the system but it works ok most of the time. 
I usually extend the desktop rather than clone.
