Comment 8 for bug 959757

now i have found where the bug is:

in gwibber-service-sina:

__init__.py

on the line4: import gnomekeyring

then i wrote a python script:
#for test
from gwibber.microblog import network, util
import gnomekeyring

when i run it:
tonychyi@tonychyi-HP:~$ python 1.py

/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

now i think there is something wrong with gwibber or gnomekeyring
