Xorg log

Setup:
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710
[Radeon HD 4350/4550]
  One DVI monitor (1920x1200)
05:00.0 VGA compatible controller: NVIDIA Corporation GK107GL [Quadro K600]
(rev a1)
  One DVI monitor (2560x1600) and one DisplayPort monitor (1920x1200)

Ubuntu Trusty
xrandr program version       1.4.1
Server reports RandR version 1.4

When I rotate the DVI monitor on the ATI card using xrandr (xrandr --output
DVI-1-1 --auto --rotate left) then X segfaults. I can however rotate the
DisplayPort monitor attached to the nVidia card without problems.
