#717 lxappearance 0.6.1 crashes on trying to remove the icon theme
After an upgrade of GTK3 and/or installing the adwaita icon theme as an obnoxious dependency of it, my mouse cursor is using the adwaita cursor theme, even for apps which aren't gtk3. I like the plain old cursors that X uses when there is no cursor theme, so looking for a way to get rid of the cursor theme I fired up lxappearance. There seems to be no way to select not to use an icon theme, so I clicked the button to try removing the adwaita icon theme, and got this:

The button to remove a GTK theme also crashes it. And I checked that it still crashes if there is more than one theme installed.
