You have been subscribed to a public bug: I had been using gnubiff in the gnome panel in Ubuntu 16.04. I recently did an in-place upgrade from 16.04 to 18.04. Now X crashes whenever mail is received.
In place upgrade from Ubuntu 16.04 to 18.04 gnubiff from package gnubiff 2.2.17-build1 In Gnome Flashback (Metacity) display manager. Add gnubiff to gnome-panel Then receive mail Gnubiff icon moves down the panel so its not completely visible. Then X dies and I'm sent back to the login page. I try login again and I'm immediately logged out again with the same error. I can login with Ubuntu ( display manager ) ok Then I can use dconf-editor to remove gnubiff from the panel org.gnome.gnome-panel.layout remove 'gnubiff-applet' from this list. After that I can login using Gnome Flashback (Metacity) without error. Then I get a ubuntu-bug popup Ubuntu 18.04 has experienced an internal error. /usr/bin/gnome-panel gnome-panel crashed with signal 5 in XGetWindowProperty() ** Affects: gnome-panel (Ubuntu) Importance: Undecided Status: New -- gnubiff applet crashes when mail is received signal 5 in XGetWindowProperty https://bugs.launchpad.net/bugs/1876609 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in Ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
