The current workaround is to disable fileinfo. You can do this by
setting $cfg->pathtomagicdb to boolean false. However, if you've got the
mime_content_type PHP library installed, it'll fall back to that as
well, and that also identifies docx files as ZIP files. So what you have
to do is apply an invalid pathtomagicdb value. This will cause Mahara to
attempt to use fileinfo, fail, and fall back to identifying the filetype
based on its file extension.

So to do that, you would put something like this in your config.php:

 $cfg->pathtomagicdb = '/dev/null';

Title:
  MS Office files being seen as zip archives

Status in Mahara ePortfolio:
  Confirmed

Bug description:
  Now that we've got file_mime_type() working with the PHP fileinfo
  library correctly, it has caused a problem. Microsoft Office 2007+
  "docx" files are recognized as zip archives by fileinfo!

  So when users upload a .docx file into Mahara, they see a ZIP icon,
  and they have the option to decompress the archive. Which they should
  not.
