[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a file with a "goog.provide('')" statement.
2. Run gjslint --strict -r . on the directory where the file resides.
3. Watch the script fail with the below-mentioned traceback.

What is the expected output? What do you see instead?
Expected output is "invalid use of goog.provide. Must provide something."

Observed output is a traceback:
*git(b:master) $ gjslint --strict -r ./
