grunt concat trying to read the inlined source map as a file name

I use browserify to bundle some files and when the 'debug' option is true it also adds a source map at the end of the file

//# sourceMappingURL=data:application/json;charset:utf-8;base64,eyJ2ZXJzaW9uIjozLCJzb3VyY2Vz...

The problem is when I concatenate this file with another one through grunt-contrib-concat, it tries to read the sourceMappingURL as a file name. So I get this error 

Warning: Unable to read "E:\xampp\htdocs\frontend\app\newportal\portal\data:application\json;charset:utf-8;base64,eyJ2ZXJzaW9uIjozLCJzb3Vy...

I tried everything I could think of, even reinstalling node/npm, with no luck.

And it used to work with the current setup. It suddenly started not working. Maybe a node module updated or something. But I tried installing the original versions(downgraded) that used to work and still no luck.

Any insight appreciated, thanks.

It appears this is related to the first part of the datauri source map that browserify generates (with debug: true) and the check that is made in the grunt concat task.

Sometimes it starts with

data:application/json;base64,

and sometimes it starts with

data:application/json;charset:utf-8;base64,

there's an extra "charset:utf-8;" in the middle there.

I don't know how that was generated, it seemed to only happen on my machine, my colleagues had no problem. And I reinstalled node and re-cloned my repo and it still reproduced. I still haven't figured out that part.

Anyway I submitted a pull request to grunt-contrib-concat, hopefully it will get accepted.
