Wrong (encoded) attachment file name for at least windows-1251 encoding

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to save attachments (like explained here) 
http://code.google.com/p/php-mime-mail-parser/ form the attached file
2. Filenames extracted by the $Parser->getAttachments() are encoded like
=?windows-1251?B?0e+z4uC6IODt8eDs4ev8IF9fxO2z7/D/7e736uBfXyAo9fPk7ubts+kg?= 
=?windows-1251?B?6uXws+Lt6Oogwi7K7vH+6ikuLkpQRw==?=

3. To convert them to real filenames I used such a trick
After the code in the example:
    $filename = $attachment->filename;
I added:
    $filenamearr = imap_mime_header_decode($filename);
    $title = '';
    foreach ($filenamearr as $element) {
        $title .= iconv($element->charset,'UTF-8',$element->text);
    }
    $filename = $title;

This saves the filenames as expected.
