[sugar] Does datastore.write() work at all?

[Benjamin M. Schwartz]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

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
