Package: xfce4-panel Version: 4.12.1-2 Followup-For: Bug #882792 Dear Maintainer,
I am experiencing this problem as well. It started after I logged out and rebooted the system for the first time in many weeks (I'm not sure exactly how long). During that time many packages were installed / removed / upgraded, though I am not sure if any of them are relevant to the problem. Specifics: The following no longer display in the notification area, though they did before the reboot: vlc 3.0.2-0+deb remmina 1.2.30.1+dfsg-1~bpo9+1 The following all continue to work fine with the notification area: network-manager-gnome (nm-applet) 1.4.4-1 xfce4-clipman 2:1.4.1-1 hamster-applet 2.91.3+git2 alltray 0.71b-1+b2 Worthy of note, vlc is QT based and remmina is GTK based, so it appears the framework used may not matter. I have tried rebooting, reinstalling recently deleted packages, deleting recently installed packages, so far, nothing I can think of works. I didn't bother with some of the things that had been tried above. etckeeper is installed, and in reviewing the git log of package changes, I didn't see any obvious issues, though perhaps someone with a better knowledge of the notification area code might see something (a relevant library?), but the section of the log that might apply (after stripping extraneous commits) is about 800 lines long. -- System Information: Debian Release: 9.4 APT prefers stable APT policy: (990, 'stable'), (500, 'stable-updates') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-6-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages xfce4-panel depends on: ii exo-utils 0.10.7-1 ii libatk1.0-0 2.22.0-1 ii libc6 2.24-11+deb9u3 ii libcairo2 1.14.8-1 ii libdbus-1-3 1.10.26-0+deb9u1 ii libdbus-glib-1-2 0.108-2 ii libexo-1-0 0.10.7-1 ii libfontconfig1 2.11.0-6.7+b1 ii libfreetype6 2.6.3-3.2 ii libgarcon-1-0 0.4.0-2 ii libgdk-pixbuf2.0-0 2.36.5-2+deb9u2 ii libglib2.0-0 2.50.3-2 ii libgtk2.0-0 2.24.31-2 ii libice6 2:1.0.9-2 ii libpango-1.0-0 1.40.5-1 ii libpangocairo-1.0-0 1.40.5-1 ii libpangoft2-1.0-0 1.40.5-1 ii libsm6 2:1.2.2-1+b3 ii libwnck22 2.30.7-5.1 ii libx11-6 2:1.6.4-3 ii libxext6 2:1.3.3-1+b2 ii libxfce4ui-1-0 4.12.1-2 ii libxfce4util7 4.12.1-3 ii libxfconf-0-2 4.12.1-1 xfce4-panel recommends no packages. xfce4-panel suggests no packages. -- debconf-show failed
