During an automated install/deinstall check the following error has happened: ERROR: Output running post uninstall script for package echo-icon-theme-0:0.1-6.fc7.noarch No theme index file in '/usr/share/icons/Echo'. If you really want to create an icon cache here, use --ignore-theme-index. Adding --ignore-theme-index to the gtk-update-icon-cache should fix the problem. postuninstall scriptlet (using /bin/sh): touch --no-create /usr/share/icons/echo || : /usr/bin/gtk-update-icon-cache --ignore-theme-index --quiet /usr/share/icons/Echo || :
Adding --ignore-theme-index would be the wrong fix, though. When removing an icon theme, there is no need to update the icon cache for the no longer existing theme directory...
Fixed in echo-icon-theme-0.2-20070223wiki.fc7
