User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2) Gecko/20081201 Firefox/3.1b2

"File > Compact Folders" somehow interferes with the Security setting of the compacted folders.

Reproducible: Always

Steps to Reproduce:
1. Run "thunderbird.exe -ProfileManager" and create a new profile, and start Thuderbird with it.
2. Create a new account. This creates Inbox, Trash, and some other mailbox files inside [ProfD]/Mail/Local Folders .
3. Quit Thunderbird.
4. Copy some existing mailbox file to Inbox. (Anything will do. Just put two or more mails in it.)
5. Open Windows Explorer, go to [ProfD]/Mail/Local Folders, right-click on Inbox and open Properties -> Security tab. Check what are listed in "Group or user names:".
6. Start Thunderbird again with the profile created in step 1.
7. Delete one mail in Local Folders/Inbox.
8. File > Compact Folders
9. Repeat step 5.
Actual Results:  
"Group or user names:" is now empty. Mails in Inbox can no longer be accessed from inside Thunderbird.

Expected Results:  
List in Security tab "Group or user names:" must remain the same.

This was a fault on my part. Somehow my [ProfD]/Mail/Local Folders had a wrong security setting, and the Inbox was just inheriting that.
I am sorry for the noise.
