Removed extra Languages when installing.
How to reproduce?
1. If there is no open document, File -> New -> Text Document
2. Insert -> Special Character...
3. Press OK in the fatal error popup window. This causes LibreOffice to exit. Popup window image at http://i.imgur.com/akkd8eL.jpg.
Had that problem with portableapps LibreOffice 5.1.0 too. Haven't tried a local LibreOffice installation.
