Hard crash when logging out of X

Description
I have a Radeon HD4650 running in a Thinkpad docking station. The T60p laptop's built-in M66GL chip has been disabled so that the HD4650 is the only graphics device on the PCI bus:
lspci:
0c:00.0 0300: 1002:9498
0c:00.1 0403: 1002:aa38
The HD4650 has two DVI adapters, and one is attached to a 1920x1200 monitor. The other is attached to a HDTV via an HDMI adapter, and the TV is not always turned on.
When Fedora 22 was first released, I noticed that the laptop crashed (hard!) whenever I logged out of X / GNOME shell, and had to be power-cycled to restart. I have now narrowed the circumstances of this crash down to when the TV is connected to the DVI port but not powered.
The laptop does not crash if either the TV is on or on stand-by, or if the HDMI adapter is physically disconnected from the HD4650's DVI port.
I have not been able to find any log files relating to the crash.
