[dataloss] drag-drop move of 100s of messages to new folder causes incorrect count


(Thunderbird :: Mail Window Front End, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv: Gecko/20060111 Firefox/
Build Identifier: Thunderbird version 1.6a1 (20060226) (Macintosh; U; PPC Mac OS X Mach-O; en-US) 20060226 Thunderbird/1.6a1

when i drag and drop a whole lot of messages (351 in one case, 275 in another case) to a newly created subfolder as archive, only the first percentage (undetermined) appear to have gotten copied to the new folder.

one way to rectify this seems to be to go to quit tb, the physical location of the folder, delete the .msf file, and then re-open tb, which rebuilds the .msf file.

Reproducible: Sometimes

Steps to Reproduce:
1. get a mail folder with a whole bunch of messages in it to move
(1a. messages may need to have been inserted in folder in non-contiguous way?)
2. choose a bunch of the messages
3. drag and drop messages to new folder

Actual Results:  
messages appear to be gone from old folder, but not all messages appear in new folder/sub-folder

Expected Results:  
messages should appear gone from old folder and all messages should appear in new folder/sub-folder

again, to retrieve "lost" data:
1] quit tb
2] find the physical location of the mail
3] delete the .msf file associated with the new folder/sub-folder
4] re-open tb
5] navigate to the folder of interest

all msgs should now appear ... hopefully ...
It happens also while moving some 50 messages from my 'news' folder to my 'savenews' folder. The 50 were chosen by a sort display on 'subject or sender'.
- some messages were moved to the existing savenews folder. All messages were deleted in de news folder. 
- undelete only worked on the messages actually moved
-I can reproduce this even when to 'from' folder only contains all 50 messages to be moved. The 'from' folder is empty afterwards, the new folder contains only some messages

-have retreived the lost messages by quitting TB, loading the news folder into notepad, setting all mozilla status lines to code 0001 (all has staus 0009), and then reloading TB. The messages appear again in the old 'from' news folder. Do NOT compact or all messages are gone for ever.

can repeat it a 't news' folder containing 136 messages
unfortunately it's to big for an attachement 500k
but must be the same with other folders of same magnitude
since I have this error with many moves of say 10 messages

in windows
Copy file in local folders as 't news'
start TB
create new folder in 't copy' in local files
Let TB determine number of messages
t copy zero messages
t news 136, 32 unread
Selct all messages in t news folder
drag and drop into t copy folder
let TB say how many messages there are in each folder
    t news zero
    t copy  32 unread total 46, which is wrong!!!
quit TB
in windows  
delet t news.msf and t copy.msf
start TB
click on both folders, let TB build msf files
and let TB determine number of messages
t copy 32 unread total 136 .... which is OK!
t news zero  which is OK!

My previous comment was about recovering the deleted mails in 't news'
