The rest is fairly cryptic. XSMP I assume means X Session Management Protocol.
What is in /tmp/.xfsm-ICE-WZX52T ? It may help to shed some light on the subject. I'm guessing that's X Free Session Management. Or what ever the XF in XFCE stands for.
What are the perms on a recursive listing of /tmp? You might also want to look at your xinitrc for XFCE. You might find the cause in there. Dunno.
It can't do any harm to remove everything in /tmp. It will probably bork your X session a little but a quick reboot should get you a clean /tmp directory to start trouble shooting the issue if it still remains. That's probably what I would do anyway.
