It's rather hard to notice, as it affects Gnome docs, BUT only for packages, that haven't been updated to new gnome-doc-utils (using gnome-doc-utils.make). IIRC, all packages, that are a part of Gnome have migrated awhile ago. omf file produced by rarian-sk-preinstall have incorrect file uri ('file:/' followed by absolute path, instead of 'file://'). The fix is obviously trivial. To observe the bug, run yelp and try to follow links from main menu to an affected package (i.e. qalculate-gtk in 'Utilities').
