Null pointer exception with missing semi colon in closures

[gpickin]

I was getting a null pointer exception of file_error - and couldn't tell why.
I finally figured out, one of the lines in my closure, was missing a semi colon, that seemed to kill the process, and result in that error, for that file.

I fixed the missing semi colon and it works now.
Might be able to be more forgiving?
