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

Took a look at other Qt5 applications like Psi+ and made a patch with similar 
workaround.
