I have this bug with i.e. the firefox-icon. It also appeared minimized in the menu-editors sidebar but I could never set it via the submenu "select icon". It also never appeared in the submenu "Icon Source -> System icons", only under "Icon Source -> Other icons".
Since the Menu Editor never accepted it, if I selected the correct one from there, I came to the Idea to move the .png files into the subfolder of breeze. When I moved them from /usr/share/pixmaps/ to /usr/share/icons/breeze/apps/48/ and rebooted the system all missing icons where in place (After I set the symlinks of firefox and thunderbird to an absolut path). Following this, it seems to me, that there is a problem within the menu- editor to use the icons present under /usr/share/pixmaps/. Oddly this only happend to me if I added KDE Plasma 5 to a already running system. In a native installed Kubuntu Xenial these icons are in place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450068 Title: Icons missing in Plasma/KDE after upgrade to Ubuntu 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-meta/+bug/1450068/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
