Description of problem:

if I stop jabberd and restart osa-dispatcher I get error
ERROR: unhandled exception occurred: (unicode argument expected, got 'str').

it is caused by

/usr/share/rhn/osad/jabber_lib.py

which contains

try: # python 3
    from io import StringIO
    from osad.rhn_log import log_debug, log_error
except ImportError: # python 2
    from cStringIO import StringIO
    from rhn_log import log_debug, log_error

which never get to ImportError in python 2

# python
Python 2.7.12 (default, Sep 29 2016, 13:30:34) 
>>> from cStringIO import StringIO
>>> sio = StringIO()
>>> sio.write(u'unicode')
>>> sio.write('str')
>>> sio.getvalue()
'unicodestr'

>>> from io import StringIO
>>> sio = StringIO()
>>> sio.write(u'unicode')
