It's not a security feature if you can disable it.

As already described in comments of the above mentioned ticket, please make
sure libmagic on your web server is configured correctly. That mainly requires

  $rcmail_config['mime_magic'] = null;

in the Roundcube config to use the defaults.

Furthermore we'd appreciate sample messages/files to further investigate
any wrong behavior of the mimetype detection.
