problem with received attachments (possible MIME issue)

problem with received attachments (possible MIME issue)

[Seb]

Hi,

For a few weeks now, some messages I receive do not display properly,
showing garbage like:

---<--------------------cut here---------------start------------------->---
RydkYXkgU2ViLA0KDQpZb3UgbmV2ZXIgY2FsbGVkLiAgRHJvcCBtZSBhbiBlbWFpbCB3aGVuIHlv
dSB3YW50IHRvIFNreXBlIC0gSSBuZWVkIHRvIHR1bnIgaXQgb24gYXMgSSBjYW4ndCBrZWVwIGl0
aW4gdGhlIGJhY2tncm91bmQgYXMgaXQgc3R1ZmZzIHVwIG15IGNvbm5lY3QgdG8gdGhlIHVuaSB2
cG4uDQoNCkNoZWVycywNCkpvaG4NCg0KRHIgSi5QLlkuIEFybm91bGQNClNlbmlvciBMZWN0dXJl
---<--------------------cut here---------------end--------------------->---

Others contain attachments that cannot be opened in any viewer, either
via 't' (`gnus-mime-view-part-as-type' and selecting the appropriate
type), 'v' (`gnus-mime-view-part' and selecting the viewer), or just
saving it to a file with 'o' (`gnus-mime-save-part') and then trying to
view it outside Gnus.  The buttons for these attachments show normally.
If I locate the corresponding Incoming* file and import it with 'G f
[path to Incoming*]', then there are no problems and the attachments
work perfectly with any method for viewing/saving.

This occurs with GNU Emacs 23.0.91.1 (x86_64-pc-linux-gnu, GTK+ Version
2.14.7) of 2009-03-08 on elegiac, modified by Debian, which is within a
couple of weeks behind CVS Emacs.  Since Gnus is part of this Emacs I'm
posting this here.  Thanks in advance for any pointers on what the
problem might be.


Cheers,

Just an update on this, in case this rings a bell for somebody.  Now
with Emacs 23.1.50.1 and Gnus 5.13 from emacs-snapshot Debian sid
package.  This is where I'm at now:

o No problems reading the body of these messages

o Attachments are listed at the end of the message, but they are not
decoded properly by any viewer, and contain only the characters
indicated in my initial message

o To decode them properly, I have to open the mbox file containing it,
save each message along with all the mime parts in it to separate files
and then do "G f" to make doc group for each of them, and reprocess with
"B r" to get the messages back to the nnml backend.

Any tips appreciated.  Thanks
