Bug#927033: libqt5widgets5: System tray icons do not appear in Xfce4

[Dmitry Mikhirev <mikhirev@gmail.com>]

Package: libqt5widgets5
Version: 5.11.3+dfsg1-1
Severity: important

Dear Maintainer,

I have recently upgraded to Buster, and I found that Qt applications don't show
their system tray icons. I use Xfce4. There's no problem with GTK apps, e. g.
icons of claws-mail, jami and parcellite are shown, but icons of Qt apps, in
particular psi-plus and hp-systray, don't appear. This does not depend on the
time when application was started: I can't see tray icons if it was autostarted
with session or later manually.
