[Ubuntu 15.04]Error when opening /var/crash with nautilus

[Guybrush88]

I get this message when opening /var/crash with a terminal and nautilus. Everything works, though.

~$ sudo nautilus /var/crash

(nautilus:2850): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

** (nautilus:2850): CRITICAL **: Another desktop manager in use; desktop window won't be created
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

Ubuntu 15.04 (vivid) reached end-of-life on February 4, 2016.

Do you still see a problem related to the one that you reported in a currently supported version of Ubuntu? Please let us know if you do and in which version otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
