Hello. I've recently started experiencing this bug after upgrading to
stretch. I can confirm that the problem has something to do with running
VLC under a non-KDE environment as was reported earlier. (In my case it
is awesomewm). If I run in a full KDE environment it does not crash.
When it does crash, it briefly displays the UI, then prints
"QSystemTrayIcon::setVisible: No Icon set" repeatedly in the terminal
before crashing.
Notable sections of a very large stack trace are below.
Last lines before the crash:

A guess, after not really spending more than a couple minutes looking at
the code, is that the call to QSystemTrayIcon::isSystemTrayAvailable()
in MainInterface::initSystray() (modules/gui/qt4/main_interface.cpp) is
returning true when the system tray is not actually available. I have
not investigated why it is that this might be happening.
Thanks for your attention.
