For some reason your /var/lib/cobbler/settings is completely blank -- 
that's probably where the parse error was.    I'm not sure how something 
could get into the
settings object that couldn't be serialized back...

/var/lib/cobbler/settings is created when you first run "cobbler check" 
after install.  

To put this file back:

# rm /var/lib/cobbler/settings
# cobbler check

and then edit the file again.

I just ran a F7 import again as a sanity check and it worked fine for me.

And yes, (to preempt the question) this settings file (unlike the other 
data files in /var/lib/cobbler) is something that really should be 
packaged in the RPM as config/noreplace and put under /etc/cobbler.   
This will be dealt with in a future release.
