I use Lubuntu 16.10. When I run evince (from a shell), I get multiple error messages such as:
(evince:14128): Gtk-WARNING **: Theme parsing error: gtk-lubuntu.css:190:21: The :insensitive pseudo-class is deprecated. Use :disabled instead.
as well as:
(evince:17673): Gtk-WARNING **: Theme directory imported-Humanity/192 of theme Lubuntu has no size field (evince:17673): Gtk-WARNING **: Allocating size to EvSidebar 0x562e8f3ee310 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
What can I do about these errors? They're annoying!
