Description

This issue seems to be a duplicate of Issue 1494 which was deemed resolved (I have commented in that Issue and will edit to reference this issue number).

While attempting to run Karma (v. 0.13.3) via Gulp (v. 1.2.1) using Node (v. 6.0.0) on OS X, there is a reported warning followed by a crash. The warning states "Cannot read property 'mtime' of undefined Use" as shown in the screenshot below.

Research direction
Investigate the file watching mechanism in Karma, specifically the 'mtime' property error. Refer to the linked issue #1494 for context. Check the relevant source files such as lib/file list.js or lib/watcher.js. Reproduce the bug with the described setup (Karma 0.13.3, Gulp 1.2.1, Node 6.0.0, OS X). Consider whether the issue is a regression from the previous fix. Look for any ongoing discussion in issue comments.
