Dropbox - Encode file names before sending

Hi

I’m getiting following dropbox error in error log. Backups are working fine. Is this a filename or doctype name error due to latin letter “ž” or is it a bug? Some guideance to point me in the right direction of searching for error is appreciated.
Running latest version on virtualbox.
