.desktop file not working

I wrote the following .desktop file for my application named Qtag: [Desktop entry] Name=Qtag Comment=Audio tag editor Exec=qtag Icon=/usr/share/pixmaps/Qtag.png Terminal=false Categories=Multimedia; Version=1.0 Type=Application I copied it to /usr/share/applications, but I still cannot find my app in the menu (I use KDE Plasma 5 application launcher). When I try to open the file in Dolphin (the KDE file manager), it says that there is no Type=... entry in the file. I use KDE Plasma 5. The executable and the icon are in the right places (qtag is in /usr/local/bin).
