I had this happen this morning after a rare reboot of one of my machines (damned Windows patches!). I don't think it is caused by dfGUI trying to start the client as I don't have that option set. When I killed dfGUI I checked filelist.txt and it was completely empty if that helps the debugging. I'm not sure if I'm using version 3.1 or 3.2 but I suspect it's still v3.1, I'll take a look when I get back home this afternoon.

I deleted filelist.txt, restarted the client then dfGUI and its running as expected now
This is similar to what I found with dfMon - if DF can't start due to a dodgy filelist, dfGui will hog the CPU and dfMon will raise a list out of bounds error...I haven't been able to trace why and as dfMon doesn't cause any other problems than the out of bounds I haven't spent too much time looking...
