It just happened again: When I opened calibre and clicked on the "convert" icon my GNOME session crashed, leaving me with the login screen. Linux was fine and even preserved my open DSL connection.
I attach my auth.log and syslog, which seem to contain a few suspicious lines, such as: * polkitd(authority=local): Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session2... * gdm-session-worker[4652]: WARNING: Unable to load file '/etc/gdm/custom.conf'... * gdm-simple-greeter[4649]: Gtk-WARNING: /build/buildd/gtk+2.0-2.24.4/gtk/gtkwidget.c:5687: widget not within a GtkWindow * gdm-session-worker[4652]: GLib-GObject-CRITICAL: g_value_get_boolean: assertion `G_VALUE_HOLDS_BOOLEAN (value)' failed Especially the assertion in the last line does not seem very reassuring to me but I have no idea what may have caused it. Grepping older logs shows, however, that this assertion was also logged on days when Gnome did not crash. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/792497/+attachment/2157657/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/792497 Title: Gnome-session crashed by various applications -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
