TypeError: Cannot read property 'mtime' of undefined

See original GitHub issue

Hi, my users get this error on Mac OS X with Karma 0.13.2. It’s this line: https://github.com/karma-runner/karma/blob/v0.13.2/lib/file-list.js#L174 where mg.statCache[path] is undefined. Here is the Karma config that is used https://gist.github.com/Sanjo/fde7bf14768d6baf16e6.

I had the same issue but solved it by changing all the file groups patterns ending from *.{a,b,c} to *.+(a|b|c)
