As per summary. I notice breakage of x11-apps/ccsm (bug #487106), but users said that some other packages also affected(media-sound/quodlibet for example, did not check this myself, though) Errors come from pygobject-2.28.6-glib-2.36-class_init.patch and upstream seems aware of this issue - just does not care. Symptom is - massive amount of messages on stderr, containing 'maximum recursion depth exceeded'
