Public bug reported:
Binary package hint: evolution
2.28.3-0ubuntu10.2
DISTRIB_DESCRIPTION="Ubuntu 10.04.2 LTS"
lenovo T61 laptop
When writing out certain attachments, Evo produces consistently corrupt
files. Co-workers using evo do not have the same behavior, and it only
started a month or two ago after years of using evo. At that time I
attempted to get evo to read mail from an exchange server via IMAP, but
IMAP was turned off on the server. I deleted the experimental account
from evo at that time.
A given email will either produce a good or bad attachment. It will be
the same bytes in the attachment file each time it is produced.
However, if I give multiple copies of exactly the same email to evo,
each instance in evo will produce the same wrong bytes each time I try
to save the attachment, but the bytes will differ from instance to
instance. This hints at a source-side as opposed to a saving-side
problem. However, see below on disabling spam filters.
There seem to be two error modes. In one, the attachment is random
trash after some number of bytes (e.g., 526), and it is 3 bytes shorter
than it should be. In the other mode, a few bytes in the file are
changed but the length is the same. The former error is doom to most
files. The latter will consistently kill anything with compression
including PDFs, but .xls and .doc files sometimes work, or mostly work.

Here, Palotai_letter.zip was from one mail instance, 2-7 were from
another, and 8-11 were from different instances. All of these files are
the same size and have a small number of errors in them. They cannot be
unzipped. For example:
cmp -l Palotai_letter8.zip Palotai_letter9.zip
51 264 64
cmp -l Palotai_letter8.zip Palotai_letter10.zip
49 325 327
50 255 327
cmp -l Palotai_letter8.zip Palotai_letter11.zip
49 325 327
50 255 327
51 264 64
To get different instances, I set evo to read a unix mailbox that was
not the system mailbox. I captured a message from our server before it
had hit evo, with all headers intact, and I copied it several times to
the unix mailbox. They appeared as repeats of the message in evo.
The only configuration changes I have made are to disable spamassassin
and bogofilter plugins and the two filtering options in mail
preferences/junk. Undoing those configs and restarting does not change
the behavior. I had been operating with those changes for years before
this started.
Mutt reads the attachments without a problem. Before anyone asks, I am
in a production environment and cannot update to a later version of
Ubuntu until later this summer.
Thanks,
