Thanks, installing libqt5libqgtk2 brought most of the icons back. Not all of them, but at least the important ones.
E.g. in dolphin, the icons in the places bar for "Root", all of the "Recently saved" entries and in the "Search for" part the icons for "Documents", "Images" and "Audio Files" are still missing. For them, dolphin still reports the "QPixmap::scaled: Pixmap is a null pixmap" message. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509562 Title: no icons for menu, folders, directories, files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/1509562/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
