[Plugin: WP-Filebase] File corruption when downloading (0.1.3.4)

Version: 0.1.3.4 (and from comments previous version too)
WordPress: 2.9.2
Server: CentOS 5.4

Files are uploaded on server OK, but downloading them corrupts data (file extension does not matter).

Opening downloaded file in hex editor, reveals, that first 2 bytes are always added as newline – 0x0D 0x0A (but file size is correct – so last 2 bytes are stripped).
For bigger files there was some more mangling (size the same).

Also, please add this for rar files:

In “/lib/wpfb_download.lib.php”
case ‘rar’: return ‘application/x-rar-compressed’;
