What went wrong

Any time I try to edit a file within a Chef cookbook, I am getting the following error:

This is also occurring any time that I toggle between insert mode...

Reproducing the bug

1. I am a beginner with VIM and just installed The Ultimate vimrc.
2. As described above, any time I try to use snippets or even just toggle between insert mode, it seems this error is popping up.

There's a lot more in the "OUTPUT_STARTS" section - I figured too much to paste here.

Appreciate any pointers (I'm almost 99% sure I am doing something wrong :) )
