Thanks a lot！it works!

in my occasion it's

sudo update-mime /usr/share/mime/
sudo update-mime-database /usr/share/mime/
sudo gtk-update-icon-cache /home/kelvin/.icons/Faenza

sudo update-mime /usr/share/mime/
sudo update-mime-database /usr/share/mime/
sudo gtk-update-icon-cache /home/kelvin/.icons/Faenza

To copy to clipboard, switch view to plain text mode 

Hi,
sorry to writing to topic one month old, but i had this problem too and found a solution, so I think it will be handy for someone:

Just run as root:

update-mime /usr/share/mime/
update-mime-database /usr/share/mime/
gtk-update-icon-cache /usr/share/icons/YourTheme

Logout/Login and it will be all right now :-)
