Few errors on the application logs, should I be worried?

I was just checking on the settings page of my outernet and noticed errors on the application logs.
I posted them here: http://pastebin.com/hyyDTJbZ

It looks like a file is missing? should I be worried? I am running ORxPi v2.7a2

We’ll look into it. It won’t crash the interface, please check that twitter feeds are updated.
