The problem was not present in 0.5.0.4 I believe the problem lies in this import construct in pyhoca/wxgui/notify.py which will fail the same way even when put alone in a file try: from gi.repository import Notify as _Notify except ImportError: import pynotify as _Notify I think the problem is that even if the GTK3 Notify module is not available, many GTK3 libraries get loaded and then the pynotify import fails with ImportError: could not import gobject (could not find _PyGObject_API object= ) This is the same exception I see when running pyhoca-gui. I think some more sophisticated GTK version selection mechanism is needed, one that would not start loading conflicting libraries. As a workaround for now I just removed that GTK3 import on my system.
