Description Thomas Haenig 2005-03-01 15:37:35 UTC
Version:           1.7.2 (using KDE KDE 3.3.2)
Installed from:    SuSE RPMs
OS:                Linux

After generating a PDF with OOs export function and sending it via kmail, I am not able to open the Attachment with acroread.

if I compare the original and the sent version, kmail seems to convert <cr><nl> to <nl>:

Original:

It does not matter whether I use quoted printable or base64 as encoding.
I would like to know for what reason ever the file is not transferred as it is?

this seems not to happen for all PDFs, but when kmail chooses "quoted printable" automatically (instead of base64)

Can you give some more information? In the message should be something like 
this:

Content-Type: application/pdf;
  name="wls-performance-hp-ux.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
	filename="wls-performance-hp-ux.pdf"

Please open the message in the source view (simply hit "V" when the message 
is selected) and post the appropriate lines (and please avoid pasting lines 
starting with a double dash and Boundary, which can mangle the message).

TIA

Sometimes, PDF files are detected as "text", even though the MIME type is application/*.

I've seen Subversion do that too.

KMail should never quoted-printable attach anything that is not text/*

Comment 6 David Baron 2005-03-02 15:42:49 UTC
Gee .. <cr><ln> --> <ln>

Does automatic windows --> unix text conversion happen when a file is copied from a FAT32 to a unix file system partition? Should it? Option? Of course, a simple file copy is not doing this, Kmail is. My vote would be not to touch the file. A VIEWING program must play with this stuff.

But, of course, a PDF file is not a straight up windows text file, is it?

Anyway, the obvious workaround is to copy the files to a linux file system and include them from there?
Comment 7 Thomas Haenig 2005-03-02 15:45:55 UTC
In my case it does not matter whether the file comes from a Windows Share or is locally created (here /tmp)

Comment 8 David Baron 2005-03-02 15:54:41 UTC
Yup. Just tested this.

I had noticed size-reduced copies but in this case, size was the same. Still got and error from acroread. An ERROR. Correspondents have received attachments which they complain were blank.

SO how might one reliably send pdf files until this is fixed?
Comment 9 Thiago Macieira 2005-03-03 02:58:03 UTC
It has nothing to do with the filesystem or CRLF -> LF conversion. It's the simple fact that a non text/* file was attached as quoted-printable.

That's wrong and not allowed.

But I have no chance to tell kMail: "this is no text you stupid software" ;-)
