I have been curious about this bug as it has persisted for several releases. Adding some info here. I am using Ubuntu 12.04 and haven't yet tested 12.10 to see if the behavior is the same.
To quickly see the lack of icons in Help --
Open a LibreOffice application, and choose Help --> LibreOffice Help
The LibreOffice Help page that appears should have two icons on it. (Pressing F1 takes you to a different page depending upon which application you are in, and none of the application-specific home pages have icons on them, though there are pages within them that do.) The icons vary depending upon which style is chosen.
I have noticed that when I open Tools --> Options... --> LibreOffice --> View
the default Icon Style says "Automatic (Tango)" and the icons don't appear in Help.
HOWEVER I find if I choose either Tango or Human styles, the icons appear in Help, and the icons persist even if I switch back to Automatic (Tango) until the next time I close and reopen the LibreOffice application.
