Crashes when devserver is deployed

[nicholsn]

I have an empty pelican site and after installing the plumage theme the devserver crashes when I launch it. Below is the error that is printed. Thoughts?

Starting up Pelican and pelican.server

@nicholsn: you had this issue because you didn't had any articles yet in your pristine Pelican site right ? In this case I just fixed the issue.

thanks for the fix, also after adding content the current version works and looks great!
