Looks like a new Ruby warning, I found these usages in YaST: ./packager/src/lib/y2packager/clients/inst_productsources.rb:357: url_string = URI.unescape(url_string) ./packager/src/modules/SourceDialogs.rb:337: params["url"] = URI.unescape(new_url.to_s) ./packager/src/modules/SourceDialogs.rb:888: path = URI.unescape(parsed.path) Fortunately only three places in whole YaST...
