SharePoint y LibreOffice 5.1

Good morning,

I'm trying to test the integration of SharePoint 2013 with LibreOffice 5.1. If you create a new document is stored without problems in the particular library , but if what I want is to edit a document already created shows me the following error:

"Failed to save the document Pruebas: General error. General error Input / Output"

Does anyone know is happening?

Thank you.

Eva.
