When I run slimbook-indicator from the command line I get the following errors:
$ /usr/bin/python3 /usr/share/slimbook/client.py $@slimbook:/usr/bin &
[Errno 2] No translation file found for domain: 'slimbook'
[INFO] (MainThread) Updating server settings...
(client.py:28602): libayatana-appindicator-WARNING **: 09:46:24.236: libayatana-appindicator is deprecated. Please use libayatana-appindicator-glib in newly written code.
(client.py:28602): Gdk-CRITICAL **: 09:46:24.442: gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed
Slimbook-indicator runs but I am a little concerned by the error "No translation file found" and "Gdk-Critical"
