bug#1574: 23.0.60; gnus fail to attach file when sending mail

[Thierry Volpiatto <thierry.volpiatto@gmail.com>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Hi, when i try to attach files with gnus, it fail with:

,----
| mm-insert-file-contents: 
| Opening input file: aucun fichier ou répertoire de ce type, 
| /home/thierry/download/#("~/download/toto.txt" 0 19 (face nil))
`----

Here is how the attached file is displayed in the body of the mail:
(i remove the "part" tags)

,----
| type="text/plain" filename=#("~/download/toto.txt" 0 19 (face nil)) disposition=inline description=test
`----

However if i modify that like:

,----
| type="text/plain" filename="~/download/toto.txt" disposition=inline description=test
`----

The attached file (toto.txt) is sent


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.
