[cobbler] tftpd.py not working after upgrading to 2.2.3

[Lassi Pölönen]

I recently upgraded my cobbler server from rhel6.2 to 6.3 and apparently
cobbler had updated as well from cobbler-2.2.2-1.el6.noarch to
cobbler-2.2.3-2.el6.noarch. The problem is that clients now seem to get
tftp timeout.

Looking at the abrt generated backtrace:

templar.py:59:__init__:AttributeError: 'NoneType' object has no
attribute 'api'

Traceback (most recent call last):
  File "/usr/sbin/tftpd.py", line 1147, in <module>
    sys.exit(main())
  File "/usr/sbin/tftpd.py", line 1125, in main
    templar = cobbler.templar.Templar(None)
  File "/usr/lib/python2.6/site-packages/cobbler/templar.py", line 59,
in __init__
    self.api         = config.api
AttributeError: 'NoneType' object has no attribute 'api'

Local variables in innermost frame:
logger: None
config: None
self: <cobbler.templar.Templar instance at 0x143ef80>


A bug in here or am I missing something? It used to work fine before and
if I change tftp module to in.tftpd, the clients will work. That's just
not a feasible option since it takes awfully long with the amount of
systems..
