As far as I understand there is a new security feature that scans the content of a zip file uploaded through the media manager and forbids the upload if that zip file contains any php files.

In my case this is pretty stupid as I want people to upload zip files containing php code, but anyway. That's not the point of this issue here.

When uploading such an "incorrect" file I would expect to at least get an error message or at a warning. Instead the page just refreshes and no message is displayed.

Steps to reproduce the issue

Go to media manager. (make sure that you have set the zip file extension in the allowed extension types) Try to upload a zip file containing php files.

Expected result

The file should upload.

Actual result

The file doesn't upload and not error message is shown. The file list just refreshes.

System information (as much as possible)

Tested on several 3.5.1 installations

Additional comments

I tried to upload the test zip files here but GitHub says "unfortunately, we don't support that file type", which is also pretty confusing as ZIP is listed as a supported file type, but it's way better than joomla's omission of an error whatsoever.
