yea, looks like they made a change in the AdminThemesController.php

 

They changed this ...

        $finfo = new finfo(FILEINFO_MIME_TYPE);
        $ext = array_search(
            $finfo->file($_FILES['themearchive']['tmp_name']),
            array(
                'zip' => 'application/zip',
            ),
            true
        );
        if ($ext === false) {
            $this->errors[] = $this->trans('Invalid file format.', array(), 'Admin.Design.Notification');
            return false;
        }

To this...

        if ('application/zip' !== $_FILES['themearchive']['type']) {
            $this->errors[] = $this->trans('Invalid file format.', array(), 'Admin.Design.Notification');
            return false;
        }

They are probably trying to remove the dependency on FileInfo extension, and failed to test that the new code would actually work.  You could try to revert that code back to the 1.7.0.2 version, but ideally you should create a forge ticket so they are aware of the issue and can fix it in the next release

        $ext = array_search(
            $finfo->file($_FILES['themearchive']['tmp_name']),
            array(
