The "close button" icons displayed in the channel list on the sidebar come from oxygen-icons, yet konversation doesn't depend on it. Result: Enabling the buttons without installing oxygen-icons creates an ugly layout. Reproducible: Always Actual Results: Ugly blank spots Expected Results: Either depend on oxygen-icons, or have konversation itself install the needed icons.
Fixed by eclass change (all packages using kde4-base.eclass now have a runtime dependency on oxygen-icons).
