From: Daniel P. Berrangé <berrange@redhat.com>

The ObjectInfo 'length' field provides the length of the
wide character string filename. This is then converted to
a multi-byte character string. This may have a different
byte count to the wide character string. We should use the
C string length of the multi-byte string instead.
