Hello I recently reinstalled Antergos and am trying to get mozc back up and running with GNOME and ibus. After installing the mozc package from the AUR I went on to try to run ibus-setup and was met recurrently with this error.

(ibus-setup:1802): Gtk-CRITICAL **: gtk_icon_theme_get_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed
Traceback (most recent call last):
  File "/usr/share/ibus/setup/main.py", line 52, in <module>
    from enginecombobox import EngineComboBox
  File "/usr/share/ibus/setup/enginecombobox.py", line 32, in <module>
    from icon import load_icon
  File "/usr/share/ibus/setup/icon.py", line 36, in <module>
    icon_theme.prepend_search_path(icondir)
AttributeError: 'NoneType' object has no attribute 'prepend_search_path'

Resetting the Ibus config and resetting my themes to default had not effect, so I’m not quite sure what I can do. Any help would be much appreciated!
