When QCoreApplicationPrivate::maybeQuit() is called, quitLockRef.load() =3D=
=3D 0,=20
hence QEvent::Quit is sent on MATE and application terminates.
KDE is fine because there is plasma-integration package, which provides=20
KDEPlatformSystemTrayIcon and quitLockRef.load() !=3D 0 when maybeQuit() is=
=20
called.

Took a look at other Qt5 applications like Psi+ and made a patch with simil=
ar=20
workaround.
