[CentOS] system-config-kickstart error Centos 6

I have noticed that if you have a %include in your kickstart file
and the include file does not exist (It's created in my %pre section) - 
- I could not even bring up
the kickstart editor.

I get an error about the file could not be opened. No reason why and 
then the editor just exists.

I had to keep chopping down my file till I found the offending line.

Hope this helps someone else...
