Subject: [PATCH 06/51] manager: gracefully handle the case of no session for
|
|
login window
|
|
|
|
get_login_window_session_id() will return TRUE with session_id=NULL when
|
|
there's no session. This restults in an assertion failure on
|
|
constructing the o.fd.login1.Manager.ActivateSessionOnSeat() arguments:
|
|
|
|
GLib: g_variant_new_string: assertion 'string != NULL' failed
