This bug is affecting me too .It didn't happened on trusty but it's back in Utopic (14.10). When I let the mouse cursor staying on the greyed browse button, a box appears where it's written that browsing is not avalaible "pysmb" not installed. But, in fact, python-smb is installed. So, it's really bad and I can't use the workaround loisted above because I don't know how to enter the path manually.
