Your system should be in a usable state then, this happens more often than I like.

Lightdm-gtk-greeter uses a different icon set. This question on launchpad explains the naming theme for the icons. I'm using lubuntu 14.04 and the aforementioned icons are located in /usr/share/icons/hicolor/scalable/places.
