Change Theme & Icons on XFCE From The CLI

So, this bug with the XFCE Appearance program is still busting balls around, not all the time, but most of the time... It simply crashes right after launching it.
Now, in order to change themes and icons without having to run the program as root, (and login out and back in) to see the freaking theme or icon change, I'm changing those via:

xfconf-query -c xsettings -p /Net/ThemeName -s "Mint-X"
xfconf-query -c xsettings -p /Net/IconThemeName -s "gnome-wise"
