I noticed that the whole set of icons (both hicolor and oxygen) is installed in /usr/share/apps/k3b/icons rather than in /usr/share/icons. Reproducible: Always
The KDE 4 application icons are in kde-base/oxygen-icons, kde-base/oxygen-icons (/usr/share/icons/oxygen/16x16/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/22x22/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/48x48/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/64x64/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/128x128/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/32x32/apps/k3b.png) kde-base/oxygen-icons (/usr/share/icons/oxygen/256x256/apps/k3b.png) And we won't put oxygen-icons as depend of k3b, it's 128 MB tarball and 30 MB install.

ok, I understand. But it is strange I've already installed the package (already several weeks) but still can not see the icon.
