Sitecore 8 Upload Zip File with Unpack options broken

Interresting topic for the day. I went on a client side for a training today and I show Sitecore capability for batch upload. Which I used quite all the time on Sitecore 7. So quite confidently, I decided to go ahead and demo it on the fly. Well unfortunately for me this did not go as planned...

I prepared my zip files with the different images, folder and subfolders

Went to the media library to upload the Zip file

Selected the unpack option

And... quite abbarassing

Well this has been reported as a bug and the workaround has been provided. If you face the same issue, you will need to edit the content of the MediaFolder.js file in the location /Website/Sitecore/Shell/Applications/Media/MediaFolder 

replace the line 320 with the following:

 //Sitecore.Support.439231
    this.yUploader.upload(file, this.destination, params);
 //Sitecore.Support.439231
