several icons not found

[Ron Smits <rons ronsmits com>]

I compiled 0.29.1 desktop finally without any problems. after starting
it up several icons are not found.
This is part from the stderr output:

** (gnome-panel:1912): WARNING **: Unable to load panel stock icon
'gnome-lockscreen'
 
 
** (gnome-panel:1912): WARNING **: Unable to load panel stock icon
'gnome-logout'
 
 
** (gnome-panel:1912): WARNING **: Unable to load panel stock icon
'gnome-multimedia'
 
 
** (gnome-panel:1912): WARNING **: Unable to load panel stock icon
'gnome-globe' 
 
** (epiphany-bin:1975): WARNING **: Web browser gnome icon not found
 
** (epiphany-bin:1975): WARNING **: Throbber animation not found

Any ideas?
