LDAP python error

[Jean-Eric C. <Jea...@li...>]

Just another thing:
When I run my program (attached), I have the following error:
Begin changing
Traceback (most recent call last):
  File "./class_test.py", line 79, in ?
    res.set("gecos", list);
  File "/usr/lib/python2.0/site-packages/python-ldap/ldap/entry.py", line
133, in set
    self.data[key] = (self.data[key][0]+values, 1)
TypeError: can only concatenate list (not "tuple") to list 

Could someone help me?
Thanks
