gnome-settings-daemon crashed with SIGSEGV in got_public_files_cb()

[nloewen]

After a few hours of use, gnome-settings-daemon will crash and reload itself repeatedly until you reboot. I have not been able to narrow down a direct cause, however it has occurred a significant number of times while freeciv does turns.
