This happens only when the applet is in-process. If I remove --with-in- process-applets=all from rules, this crash no longer occurs.
Also, just before the crash happens, I get this warning: Failed to register object /org/gnome/panel/applet/ClockAppletFactory: An object is already exported for the interface org.gnome.panel.applet.AppletFactory at /org/gnome/panel/applet/ClockAppletFactory -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/1362476 Title: gnome-panel crashed with SIGSEGV in panel_applet_get_xid() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/1362476/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
