Solve the following python programming problem given the following code:
def properties_loader(filename) : 
    split_pattern = re.compile ('[=:]') 
    def parse_line(line) : 
        line = line.strip () 
        if ((not line) or line.startswith ('#')) : 
            return 
try : 
            (key, value) = split_pattern.split (line, 1) 
except ValueError : 
            msg = ('Invalid properties line: %s' % line) 
            raise errors.ConfigurationError (msg) 
return (key.strip (), value.strip ()) 
with open (filename) as fh : 
        return dict (filter (None, (parse_line (split_pattern) for line in fh))) 

    
    

    Fix the buggy line: return dict (filter (None, (parse_line (split_pattern) for line in fh)))
