If "Save As", different result was obtained.
(1) filename="pdf-file-01.pdf", Content-Type: =?iso-8859-1?q?application/pdf
    Message Body text was saved to .pdf file.
> <div class="moz-text-plain" wrap=true graphical-quote=true style="font-family: -moz-fixed"><pre wrap>
> Messae body text - line 001
> Messae body text - line 002
> Messae body text - line 003
> </pre></div>
In any other case including case (3), abc?def/pdf, data of correct part was saved.

It looks that, even "Save As", part number(&part=1.x in internal location) is lost if multiple "?" is used in MIME type string.

Phenomenon of comment #1 is perhaps due to "=" in mime-type.
Internal URL is one like next.
  ...?keyword1=value1&...&keywordN=valueN&...&keywordP=valueP
      for example,
        &type=mime-type : mime-type == major-type/minor-type  
        &name=file_name
        &part=part_number
(a) Any of "?", "&", "=" in mime-type value should be escaped in internal URL used by Tb.
(b) Tb should process "major mime-type only without trailing slash" correctly. (c) For file_name, file_name value should be quoted by double-quote if not quoted by '"', in case of "?", "&", "=" in file name value without quoting by '"'(known bug).

For Content-Type: =?iso-8859-1?q?application/pdf case(RFC2047 is wongly applied, string after last ? is correct mime-type), fix was proposed to Bug 659355.
Setting dependency.

FYI.
bug 335263 is for "row & in filename" case.
