Unity Settings Deamon crash in 16.04 every time after boot

安装ubuntu 16.04的时候，出现这样一个错误：

 unity-settings-deamon crashed with SIGSEGV in up_exported_dae (can't read more since there is no word wrapping).

网上查了资料，反复验证之后，发现这个是可以解决这个问题的：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install --reinstall unity-settings-daemon
sudo reboot
