Unfortunately the backtrace is lacking debug symbols as normal on Archlinux. This makes it impossible to further investigate. What we see from the backtrace is that it crashes inside the proprietary nvidia driver.
Thanks for your feedback. I didn't look at the backtrace myself. This makes sense, since I installed a nvidia driver update just one day ago and never had this issue before. So I think you'll be right and the issue is caused by a problem within nvidias driver... one more time :-( I hope there will be a fix released by nvidia soon. Otherwise I'll have to got back to the previous version. I think you may close this issue. Sorry for bugging you with that request. I'll be more careful next time before submitting a bugreport.
