Breeze icon set is missing many icon aliases like application-sql, chromium (there is only chromium-browser one and some distros call it only chromium), skrooge, QtCreator and so on. I think the icons created using Ubuntu's naming scheme (because the work/displayed on Kubuntu). Most of the time ArchLinux uses nearly vanillia packages. They must work with vanillia packages' .desktop file. An empty icon in Dolphin also is not displayed for unknown files. Reproducible: Always
True so true. But unfortunately no one seems to care for this problem(yet).... :(
