I had this problem this morning after logging in the same. Except my computer was waking up from hibernate when I got the fatal error message. Apport asked me to report a bug. I was about to post a new bug report, but I saw this one as a suggested, so I said "mark this as affects me also". Though now, I dont know which logs you may be interested in seeing. So, I just attached the ones in your comment.
##### MOMENTS BEFORE POSTING ##### Also, I just did everything you said and restarted and got the FATAL ERROR message again. So, let me know what you wanna see from that. Though from the CLI I got this output upon clicking connect : $ ubuntuone-client-applet ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/status: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ERROR:dbus.proxies:Introspect error on com.ubuntuone.SyncDaemon:/status: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 ** Attachment added: "log_old.tar" http://launchpadlibrarian.net/39960403/log_old.tar -- UbuntuOne reported fatal error on booting up. https://bugs.launchpad.net/bugs/528379 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
