ReferenceError: item is not defined

I'm getting this error in the project I'm working on:

```

```

Everything works like a charm after I issue `npm install`, app works for a while, and then for unknown reason it breaks with all this stuff in stdout. I'm using `compound@1.1.13-1` with node v0.10.28,

Any ideas?

The error occurs in compound/lib/server/structure.js at line 121 where 'item' is not defined. Start by examining the readNode function and its context to understand how 'item' should be declared. Check the loop structure and variable scope. Run the project to reproduce the error, then trace through the loadStructure initialization to see what triggers the undefined variable.
