Comment 9 for bug 188542

This is an icon theme problem (whichever theme you happen to be using), not a Nautilus problem. Nautilus (actually GIO) is following the Icon Naming Specification from FreeDesktop.org (http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html ) for finding icons, and many old themes have yet to upgrade their icon names to be compliant with this standard. Fixing the themes can be done via symlinks if necessary. GIO also can look up old icon theme names now, but this functionality should probably go away in the future and themes SHOULD migrate as soon as possible (http://svn.gnome.org/viewvc/glib?view=revision&revision=6557 ).
