Nuxeo Drive crash / freeze when Nuxeo Document is created with a filename with non ascii character

Steps to reproduce:

• Bind to server and synchronize a workspace
• Create a document of type File in Nuxeo DM web UI
• Edit the document and upload a file with an accentuated char using the [Browse...] button from the browser (in this case chrome under OSX)

Expected:

• the new file shows up in the Finder of the client

Observed:

• Nuxeo Drive stops synchronizing anything (looks like a freeze)
• the logs show an error in the get changes operation call: the json is truncated hence invalid.
