230888 - Non-existing folders marked as having messages, including new ones

Status: VERIFIED FIXED

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Aleksey Nogin]

I have a number of folders named "INBOX.Sys.xyz" (this is Courier-IMAP, it uses
"." as a folder name separator), but no folder named "INBOX.Sys". As expected,
in the folders pane, "Folders" is greyed out.

Everything was working fine with BuildID 2003102322 (trunk). But after I've
upgraded to BuildID 2004011221, I am seeing:

- From time to time, the "Sys" "folder" (and other similar greyed-out
"non-folders") would get marked as having new messages (e.g. the folder icon
would change).

- From time to time, in addition to "new messages" icon, the folder would get
non-zero message counts. Almost always, the message counts would be # unread = #
total = # of unread in another (real) folder! For example, I have Work.PRL
folder that currently has 44 messages unread from 53 total and from time to
time, Sys would be shown to have 44 unread and 44 total messages. But sometimes,
Sys would "steal" the unread count from some other folders - sometimes even from
a folder in _another_ IMAP account.

Note:

- The folder name still always stays greyed out. 

- Quitting Mozilla, erasing the .msf and restarting does not help - initially 
the folder is shown correctly, but that quickly changes.

- If I click on the "Sys", the "new messages" icon gets replaced with the normal
one, but the bogus counts stay. Once Mozilla actually showed me headers from
another folder when I did that, but after erasing the .msf this did not happen
again - now the headers pane always (correctly) stays empty when a "non-folder"
is selected in the folders pane.

- Sometimes the counters would disappear and the "non-folder" would be shown
normally, but later they would come back.

- I have user_pref("mail.check_all_imap_folders_for_new", true); and some
non-INBOX folders are have "check this folder for new messages" enabled.

- I am running Fedora Core 1 (+ all updates). I have compiled Mozilla on Fedora
Core 1 with --enable-default-toolkit=gtk2 --disable-freetype2 --enable-xft
--enable-optimize=-O2 --disable-debug --disable-strip-libs --disable-tests
--enable-xinerama --enable-nspr-autoconf --without-mng --enable-crypto
--disable-xprint --without-system-nspr --with-system-zlib

I did not hae a chance to test this yet, but is this something worth checking

Something very similar to this bug came back (but this time it's empty folders
that get marked wrong, not the non-folders) - see bug 239196.
