When I call datastore.write(jobject), my program dies, producing the
appended logfile. The error is
~ File "/usr/lib/python2.5/site-packages/olpc/datastore/datastore.py",
line 177, in _resolveMountpoint
~ mp = self.mountpoints[mountpoint]
KeyError: dbus.String(u'1285c87a-1b13-4463-9e19-87f0ad8e1828',
variant_level=1)
This is very mysterious to me.
Please help,
Ben
