With Ubuntu 13.10, I connect to two different OwnCloud installations and can browse for only a few seconds before it freezes the connection and stops working. When I try to reinstate the connection it fails to even ask for the password (Ubuntu was told to forget the password). I did check the webdav connection through Firefox on two computers and ES File Explorer on android. I know that this isn't a webdav problem and don't know what is happening in Ubuntu to stop being able to read the connection.
