Hello, everyone.
I got annoyed about kbuildsycoca4 complaining about a missing Exec= line in /usr/share/applications/qemu.desktop , so I decided to file a bug in qemu about this
https://bugs.launchpad.net/qemu/+bug/1868221
However, qemu guys say that kbuildsycoca is wrong about interpreting .desktop files, and that apps with "NoDisplay" should not be reported.
I don't have the fresh kbuildsycoca though (I presume kde5 does have something like it?). Who can check if kde5 complains about a wrong qemu.desktop?
If it does, I'll file a bug in KDE.
