Please describe the problem:
After triggering bug ID 527729 (downloading messages from POP3 a after they've already been grabbed), the mailer shows multiple messages differently in the list.

For example, I may have the following emails:

1: Email from CVE editor
2: Email from friend with link to news article


Evolution has downloaded email 1 and 2 each twice.

If I view the first copy of email 1, I see the correct message displayed.
If I view the second copy of email 1, I see the message for email 2.

If I view the first copy of email 2, I see the correct message displayed
If I view the second copy of email 2, I see yet another email (a 3rd one)

The third email is also a duplicate. and this pattern continues throughout the entire set of messages.


Steps to reproduce:
1. Trigger bug ID 527729
2. View the first of the duplicate messages
3. View the second of the duplicate messages


Actual results:
The wrong message is displayed on step 3.

Expected results:
I would expect the same thing to be displayed for steps 2 and 3.

Does this happen every time?
Yes, 100% consistency. Easily reproducible.
