Evolution fail to decode TNEF attachments

[David Girault]

When receiving an email from user using outlook, the attached files are grouped all in one tnef file.

The content-type of this part of the email is as below:

      Content-Type: application/ms-tnef; name="winmail.dat"

Old version of evolution decode correctly this kind of email up to version 3.4.0 of evolution when TNEF attachement are handled bu evolution plug-ins. At this time, the TNEF plugin handle mime_type = "application/ms-tnef" and "application/vnd.ms-tnef".

Since this commit for evolution 3.5, https://git.gnome.org/browse/evolution/commit/?id=931191474643164e96b5778c790e42cca517e729, the mime_type handled by the TNEF module are "application/ms-tnefl" and "application/vnd.ms-tnef".

There is an additionnal letter 'l' that prevent this module from working correctly!!!

After patched the binary file directly with the following command, it's work again!!!

sudo sed -i 's#application/ms-tnefl#application/ms-tnef\x00#' /usr/lib/evolution/3.10/modules/module-tnef-attachment.so

David,

Thanks for submitting a patch for this. I see this has been fixed upstream, however I can't confirm if this fixed has landed. Which version of Ubuntu GNOME did you report this against, 14.04 or 14.10?

[Bruce Pieterse (octoquad)]

I had a look at the module-tnef-attachment.so and can still see it present in 14.04.1

[Bruce Pieterse (octoquad)]

This is still present in 14.04.3 but has been fixed in 15.04.
