Comment 11 for bug 741387

Not an issue in GTK+ at all. In a brief moment of lucidity, I tried to generate icon caches for each of the subdirectories:

sudo find . -type d -print -exec gtk-update-icon-cache -ft /usr/share/icons/ubuntu-mono-dark

Only the animation directory fails. Turns out there are duplicate symlinks for the nm-stage02-connecting03 icon.
