The expression used for 'includeexpr' (which is triggerd by [+I or insertion completion, as specified by default in 'complete') fails if b:node_root is undefined.
The b:node_root variable is created by the node#initialize(), which is called from s:detect() when it detects that the file is part of Node.js project.
A possible solution is to avoid change anything (as the 'includeexpr' option) if a file isn't detected as node file. Maybe it is also possible to improve the detection by searching the buffer for some node specific keywords (such as require) and setting the b:node_root to the env variable $NODE_PATH instead of leaving it undefined.
In any case, I didn't understood the need for all the autocmds in the end of the plugin/node.vim, and while debugging the E121 error I noticed that s:detect() is called for every buffer opened, including the help files, which causes unnecessary overhead. I've implemented a simpler solution, but it is possible it missed some corner case.
I intended to run the automated tests, but I'm not familiar with ruby. Did you have the chance to write the post explaining the tests which is mentioned in #4?
