I ran "sudo ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash" and I get the errors:
1) on terminal: Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
2) on gtk window: Error('Incorrect padding',)
Although somehow, maybe after some recent update, problem was solved!
