Windows XP

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Build Identifier: version 1.6a1 (20060117)

I created a subfolder (say 'sf') in 'sent' folder
I moved 8 mails from 'sent' to 'sf'
'sf' showed 3 present mails (o.c. wrong) but 13 Mb size (correct)
(fyn the three mails are 4kb, 375 kb, 378 kb big)

Before posting I tested:
I moved a 10 Mb mail from 'sent' to 'sf'
- 'total' value and num of displayed mails did not change
- 'size' value correctly increased
I moved a 1 Kb mail from 'sent' to 'sf'
- this was correctly added to the 'total' value and it is displayed

Reproducible: Sometimes

Steps to Reproduce:
1. made subfolder in 'inbox'
2. moved small file, it worked
3. moved big (6 Mb) file, it's there (mbox size increases) but doesn't show

Actual Results:  
(best described above)
Small mails are shown, big mails are not shown

Expected Results:  
(best described above)
(Ceteris paribus) every mail in the mbox file should be shown in the list

I also checked if this bug shows with incoming mails - I correctly received and displayed a 6.3 Mb mail.
I tried to move it in 'sf' and it worked - it is displayed (!) 
I so tried with an old mail again and it is now correctly displayed (!!)
The previous 'hidden' ones are still hidden
Don't know if it is the same bug ...
But ... it could be ...

Thunderbird 2.0b1pre 2006101803

--> mails in Local Folder --> XXX --> YYY (subfolders)
I was, by using drag and drop, moving +/- 30 emails to subfolder
Local Folder --> XXX --> ZZZ --> WWW

These 30 emails contains attachment like jar files, or doc and pdf

But the emails disappears ... only a very few of them was there ...
--> close TB
--> open TB
--> always there

--> compress folder WWW --> no effect
(and no effect on WWW.msf and physical WWW mbox folder)

--> close TB
--> delete WWW.msf
--> open TB
--> and the emails was there ... 

It was the first time i saw that ... and i'm using Branch 1.8.1 for more than 6 months ...

Cannot find an other bug in bugzilla matching a drag and drop disappears of mail a part this one ...
cannot succeed to reproduce it with the same group of mail :-(
Summary: some moved bulky mails disappear → some moved bulky mails disappear (corrupted .msf file)
Confirmed as reported by

1) sending to you a mail with a big attachment (for me: 6.3Mo) ... if your smtp accept it ...
2) receive the mail
3) drag and drop to an other folder 
In my case the mail goes by filter to Local Folder --> XXX --> YYY (subfolders)
and i try to drag and drop to Local Folder --> XXX --> ZZZ

--> the mail doesn't appear ...
--> the mbox file was increased by 8Mo
--> compacting the folder has no effect
--> only way to solve the problem: Close TB and delete the ZZZ.msf file

Some interesting comments:
1) Using right-click--> Move To : no problem
--> the problem comes only with drag and drop
2) Drag and drop to trash --> no problem ...
Ever confirmed: true
Cannot test on ... so setting version to 2.0
Is somebody can test on
