Earlier on this evening I was asking the very excellent Ted Gould about a weird problem with my Gtk+ icon theme - an app I'd previously installed by hand in /usr/local/, but subsequently removed, had broken icons because Gtk+ was looking in /usr/local/share/icons/ instead of /usr/share/icons/. We did a little digging and realised I had an icon theme cache file in /usr/local/ that was overriding the one in /usr/. A bit of deleting later and it's back, but in the process we whipped up a little bit of python to print out the filename of an icon given an icon name.
