parcel-tracker не запускается

ubuntu 11.10
в лог кладёт:
parcel-tracker[1483]: segfault at bf40ef50 ip 0050b479 sp bf40ef4c error 6 in libc-2.13.so[4c9000+17c000]

при запуске говорит:
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
import gobject._gobject

from gtk import _gtk
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed
from gtk import _gtk

как его победить?
