[development] patch for flexinode 4.6.x

[Robert Garrigós Castro]

There is a patch for flexinode 4.6.x ready to commit 
(http://drupal.org/node/21673) which I would have done it my self if I 
had permission (I have permission to commit on contributions repository 
but I guess only for head). I know that everybody, as well as myself, is 
quite concentrated on 4.7 but this is a quite old flexinode's bug. We 
should not forget 4.6 as it is the actual stable release. Can somebody 
with permission look at it and commit if it's ok?

Thanks.

Robert.
