383308 - Removing tag does not remove label (X-Mozilla-Status2 not updated) - tag migration issue

Status: NEW

(MailNews Core :: Database, defect)

Description

[Lorenz Froihofer]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
Build Identifier: version 2.0.0.0 (20070326)

As far as I know, if a message was assigned a label in Thunderbird < 2.0, this was stored in X-Mozilla-Status2. TB2.0 recognizes this information and converts the label to the corresponding tag (for displaying the message). When removing the tag, TB does not update the X-Mozilla-Status2 entry and thereby the label is still present in the source of the message while no longer being displayed (due to the entry in the corresponding *.msf file). If you now delete the "*.msf" file of the mail folder where this message is stored and it is re-generated upon the next start of TB, the message will still have the label assigned (X-Mozilla-Status2) and this will be shown again.

--> Every time the *.msf file is re-generated, one has to remove the tags from all messages that previously were assigned labels in TB < 2.0.

Reproducible: Always

Steps to Reproduce:
1. Take a message that was assigned a label with TB < 2.0
2. Remove the label with TB2.0
3. Close TB
4. Delete "*.msf" file corresponding to mail folder containing the above message
5. Start TB
5. Look at the previous mail
Actual Results:  
E-mail message is shown with a tag corresponding to the label assigned previously with TB < 2.0.

Expected Results:  
E-Mail message should not have a label or tag assigned.

Attachment: Mailbox file illustrating the problem

The issue is still present in TB beta3.0pre4. Close Thunderbird and copy the attachment to the "Local Folders" directory of your Thunderbird profile. The new Mailbox "example" should appear. Then follow the initial bug description to reproduce the bug.

Can confirm on Linux with TB 3.1.9 and 3.3a3.
Updating component, it is a problem with the mailstore (not migrating from other client).

This still exists in TB 8.
