Details

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.1b1pre) Gecko/20080925121544 SeaMonkey/2.0a1
Build Identifier: Thunderbird Version 2.0.0.17 (20080914)

If you have the "sort by threaded" view enabled and move some previously threaded messages into another folder, the threading gets lost.

This happens if
- the messages are moved individual, one after another, newest first, oldest last, and
- either the messages have different subjects or mail.strict_threading is set to true.

Reproducible: Always

Steps to Reproduce:
1. You need some threaded mails in your inbox. If necessary, mail to yourself and respond to that mail. Make sure you change the subject when replying (e.g. like german language Outlook does with adding "AW:" instead of "Re:"). Alternatively you can set mail.strict_threading to true to trigger this bug. Now you have a threaded structure like this in your inbox:

testmail1
|- Re: testmail2

2. Move the last message, the reply "Re: testmail2" to another folder.

3. Move the first message "testmail" to the same folder.

4. Change to that folder (and enable the threaded view, if not already done).
Actual Results:  
The messages are displayed unthreaded in a flat hierarchy:

testmail1
Re: testmail2

Expected Results:  
Messages should be threaded again.

It is possible to regain the threading by moving the mails to another folder again. Same procedure, each at a time, but this time moving the oldest message(s) first.

This bug happens with Thunderbird 2.0.0.17 as well as with SeaMonkey 2.0a1.
Hmpf. Just discovered bug 181446, which seems to cover exactly the same issue. But bug 181446 has been fixed on the trunk more than one year ago. Why do I still see it in SeaMonkey 2.0a1? Has SeaMonkey 2.0 branched from the trunk before 08/2007 or is this bug still present?
Downloaded the Thunderbird latest trunk nightly, and I still can reproduce this bug with
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.1b2pre) Gecko/20081029 Shredder/3.0b1pre
Finally, after reading all the comments in bug 181446, I relised that I have to set mail.correct_threading to true for the fix to become active. So this bug is in fact a duplicate of bug 181446. *sigh*
