Gedit launched from terminal : Gtk-CRITICAL **: gtk_window_set_default: assertion `gtk_widget_get_can_default (default_widget)' failed

[Scuderi Giovanni Luca]

I launch gedit from terminal and it shows:
(gedit:11995): Gtk-CRITICAL **: gtk_window_set_default: assertion `gtk_widget_get_can_default (default_widget)' failed

if I open a file:

(gedit:12698): Gtk-CRITICAL **: gtk_container_remove: assertion `gtk_widget_get_parent (widget) == GTK_WIDGET (container) || GTK_IS_ASSISTANT (container)' failed

if I click file open ... on show of file picker:
(gedit:12698): Gtk-CRITICAL **: gtk_tree_selection_get_selected: assertion `GTK_IS_TREE_SELECTION (selection)' failed

After i do it at first time, no more error messages are spammed.

If i close and i re-open, same story.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

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 otherwise this bug report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
