I don't know how to wait for a dialog to close, but I have way to get selected 
filename without knowing it.
I simply connect to "selection-changed" signal.
Here is sample signal handler (self._fcbLogs is a FileChooserButton):

def _onFcbLogsSelChanged(self, widget, data=None):
    dir = self._fcbLogs.get_filename()
    if dir is None:
        return
        
    dir = unicode(dir, u'utf8')
    self._config.logsPath = dir
