As digikam at the moment stores it's high quality icons only in the oxygen icon theme, unity and gnome will not find them by default. So please try:
# Copy digikam icons from oxygen to the fallback hicolor theme. cd /usr/share/icons/oxygen sudo rsync -vR */apps/digikam.png ../hicolor
If not found: sudo apt-get install oxygen-icon-theme try teh rsync again.
Logout/in and try again.
If one still sees the ugly icons, move them to a location that is not searched, e.g., your home dir
sudo mv -v /usr/share/pixmaps/digikam*.xpm $HOME/
