Can't load plugin in f22 with Chinese locale

[hizukiayaka]

Hi, my language environment is zh_CN.utf8, with using the latest version 0.7.0-1 in dnf
I will got
Traceback (most recent call last):
File "/bin/dnf", line 36, in
main.user_main(sys.argv[1:], exit_code=True)
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 198, in user_main

File "/usr/lib/python2.7/site-packages/dnf-plugins/system_upgrade.py", line 359, in init
super(SystemUpgradePlugin, self).init(base, cli)
TypeError: must be type, not None

But if I use the LANG=C, it would work

Another traceback related to Chinese locale:

The user says:

I comment off the line 368 and 368 in /usr/lib/python2.7/site-packages/dnf-plugins/system_upgrade.py
,then the problem is solved and my os updates to fedora 23 successfully

Also affects ja_JP.utf8 and de_DE.utf8, so possibly all languages which use more than 7-bit ASCII characters.

It looks like (at least part of) this is a problem in upstream DNF - see rpm-software-management/dnf#375 for more info.

PR #34 technically fixes the problem but since dnf.i18n.ucd* are being deprecated I'm inclined to try to find a solution that doesn't rely on that.
