Lucid indicator icons are not shown. Displays the "unknown icon" instead

This is not an indicator applet bug. its the icon theme you are using which apparently dont seem to have the icon for indicator sound. Its gnome-icon theme.

True, I had not thought about that.
Though, the icon disappeared some days ago, I don't remember when, after an
upgrade. Before that, I had no icon problems.

The issue is an indicator-sound one which doesn't use fallback icons

http://library.gnome.org/devel/gtk/stable/GtkIconTheme.html, using gtk_icon_theme_lookup_icon() with the fallback flag set should be working, the spec has also be updated to use audio-volume-low-null which should fallback nicely

The API (Liblindicator) which the inidcator-sound uses expects a GtkImage as the icon. GtkImage does provide the same fall back mechanism which Sebastian has pointed to above with GtkIcon. It is a known issue across all indicators and one which will need to be resolved shortly.

pulling bug state from 533026, which I'm marking as a duplicate.

Fixed with the use of the new indicator_image_helper call. Released in indicator-sound-0.1.3

that fixed my icons that wasn't showing at all for sound and battery on Clearlooks theme

Can't mark the following bug:
https://bugs.launchpad.net/indicator-applet/+bug/543592
as a duplicate, but it is, and that one is now invalid.

bug #543592 is a duplicate of bug #542365, so you need to edit the duplicate status of the first and then mark the second as a duplicate.
But I don't understand why you think #542365 is a duplicate of this, as it is related to the volume applet, not to the volume icon

i also have the same problem after uninstalling gnome
