Comment 10 for bug 591998

I am the developer of ibus. In ibus im context, gtk_im_context_filter_keypress works in async mode. It means gtk_im_context_filter_keypress will always return TRUE. And if the ibus imcontext does not handle the key event, it will use gdk_event_put to send the event back to client windows.

I guess the problem is because of gnome-do does not use gtk_im_context_set_client_window to set client window correctly. Please check it.
