After kde upgrade to QT 5.8.0, launching an application from the panel icon raises an annoying windows xp like window asking if I trust the program. see screenshot: https://framapic.org/8acmhBU8cfoo/Kj8zD2JFwNMv.png Clicking "continue" fails to launch the application and raises an error "Service '/home/username/.local/share/plasma_icons/firefox.desktop' must be executable to run." This happens because the .desktop files are stored outside of ~/.local/share/applications/ which seems to be blacklisted for execution when /home is mounted with noexec flag. Bug replication: 1. mount /home with noexec flag: mount -o remount,exec /home 2. click on application icon from panel Fix: 1. move the ~/.local/share/plasma_icons directory to ~/.local/share/applications/plasma_icons: mv ~/.local/share/plasma_icons ~/.local/share/applications/ 2. add a symlink to the plasma_icons directory to ~/.local/share/: ln -s ~/.local/share/applications/plasma_icons ~/.local/share/plasma_icons archlinux forum post for reference: https://bbs.archlinux.org/viewtopic.php?pid=1698141#p1698141
I think this has been fixed; feel free to reopen if you still have this issue.
