Edited Issue: Analysis caused crash? [1375]

Using build 20903.00, VS 2013 Update 3
Edit: Not related to task explorer extension (repros without it)

Create starter express project.
Add new blank JavaScript file named grunt.js to project.
Close solution, save when prompted.
Reload solution and wait a few seconds.
If it doesn't repro, restart VS and reload solution.
